Circuit Description ----- 47 CFR. 2.1033(c)(10) This section provides the description of circuits required by 47 CFR 2.1033(c)(10). The following are included: 4.1) Carrier Frequency Generation and Stabilization 4.2) Digital Modulation Technique 4.3) Modulation Limiting and Post Limiter Filter 4.4) Means for Output Power Limiting 4.5) Spurious and Harmonic Emissions Suppression Applicant: Motorola Inc FCC ID: AZ489FT5797 IDEN, Motorola Inc., 8000 Sunrise Blvd., Plantation, FL 33322, USA WWW.MOT.COM/iDEN Page: 4- 2 4.1.Carrier Frequency Generation and Stabilization The synthesizer reference oscillator employs a crystal controlled Colpitts oscillator running at a frequency of 16.8Mhz. The oscillator transistor, start-up circuit, and temperature compensation circuit are located in the U301 while the oscillator feedback capacitors, crystal, and tuning varactor are external. This oscillator is temperature compensated to an accuracy of +/-2.5PPM from -25 to 60 degrees C. The method of temperature compensation is to apply an inverse Bechmann voltage curve which matches the crystal's Bechmann curve to a varactor which constantly shifts the oscillator back on frequency. The crystal vendor characterizes the crystal over a specified temperature range and codes this information into an eight-digit code which is printed on the crystal package in a bar code. In production this crystal code is read via a 3-dimensional bar code reader into a custom temperature compensation tuning algorithm. This tuning algorithm decodes the crystal information and takes voltage and temperature measurements on the oscillator then programs U301’s temperature compensation registers to provide the specified frequency error vs. temperature performance. Y300 U301 AFC & TEMP ADJ. Figure 4-1: 16.8 MHz Reference Oscillator The reference oscillator runs at 16.8 MHz. The signal from this reference oscillator Applicant: Motorola Inc FCC ID: AZ489FT5797 IDEN, Motorola Inc., 8000 Sunrise Blvd., Plantation, FL 33322, USA WWW.MOT.COM/iDEN Page: 4- 3 is routed to the synthesizer IC (U301) and is used to control the stability of the main Voltage Controlled Oscillator (VCO) which oscillates at a frequency between 956.9- 971.9 MHz (see figure 4-2). The synthesizer also buffers the 16.8 MHz signal and provides it as a clock signal to U401 (A/D and D/A IC), U501 (TX Quadrature Modulation and Linearization IC), U601 (Quadrature Receiver IC), U001 (DC Power and Audio IC) and U801 (Controller and DSP IC). The PLL inside the U601 uses the 16.8 MHz clock as the reference for the TX Offset VCO and RX 2nd LO VCO. The frequency of the TX Offset VCO is 301.8 MHz which is divided by two in U501 and mixed with the main VCO to generate the transmit frequency. The frequency of the RX 2nd LO VCO is 219.3 MHz which is divided by two in U601 and mixed with the received Intermediate Frequency (IF) signal to generate the baseband data for the DSP. The frequency control for each VCO is accomplished by a PLL inside U601 which compares the VCO frequency (after a frequency divider) to the reference frequency thus phase-locking each VCO to the reference oscillator. The transmitter frequency is programmed to a single frequency between 806-821 MHz composed by subtracting half of the TX offset VCO frequency (301.8 MHz) from the main VCO frequency 956.9-971.9 MHz. The subtraction is done by a mixer in U501, followed by a band pass filter (FL501) which selects the transmitter frequency of 806 - 821 MHz from the other mixing products and rejects spurious signals. ∏8 Clock Generation 16.8MHz 16.8MHz SYNTHESIZER IC 956.9-971.9 MHz Transceiver Frequency Generation Subsystem Main VCO 956.9-971.9 MHz 16.8MHz Reference Oscillator 16.8MHz ∏8 ∏ 1 150.9 MHz 806-821 MHz SYNTHESIZER Phase-Detector and Filter ∏ 2 109.65 Mhz U301 U501 U601 ∏ 2 TX Offset VCO 301.8 MHz RX 2 nd VCO 219.3 MHz Figure 4-2 : Transceiver Frequency Generation Subsystem 4.2.Digital Modulation Techniques Applicant: Motorola Inc FCC ID: AZ489FT5797 IDEN, Motorola Inc., 8000 Sunrise Blvd., Plantation, FL 33322, USA WWW.MOT.COM/iDEN Page: 4- 4 The subject radio makes use of 3 different modulation techniques termed Quad- 16QAM, Quad-64QAM, and Quad-QPSK. In voice mode, the radio will function in Quad-16QAM mode only. In data mode, the radio will use any one of the three different modulation techniques (Quad-16QAM, Quad-64QAM, and Quad-QPSK) in a given slot. The following describes each of the modulation techniques: The modulation technique termed Quad-QPSK is a linear digital modulation of a multi-channel variant of Quadrature Phase Shift Keying (QPSK). Data bits to be transmitted are split into four parallel lower rate streams, each of which is QPSK modulated to its own sub carrier frequency. The four resulting sub channel signals are then combined in frequency division multiplex fashion to produce the composite M-QPSK signal. This spectrally efficient linear modulation can achieve transmission at 32K Bits per Second in a 25 kHz channel. The transmitter is configured using TDMA time slotting so that up to 6 radio users can simultaneously share the 25 kHz channel. The modulation technique termed Quad-16QAM is a linear digital modulation of a multi-channel variant of a 16-state Quadrature Amplitude Modulation. Data bits to be transmitted are split into four parallel lower rate streams, each of which is 16QAM modulated to its own sub carrier frequency. The four resulting sub channel signals are then combined in frequency division multiplex fashion to produce the composite M-16QAM signal. This spectrally efficient linear modulation can achieve transmission at 64K Bits per Second in a 25 kHz channel. The transmitter is configured using TDMA time slotting so that up to 6 radio users can simultaneously share the 25 kHz channel. The modulation technique termed Quad-64QAM is…

No antenna is provided with the modem, so a user must obtain the antenna separately. Three (3) dB gain (relative to a quarter wave whip, 2 dB relative to the dipole reference used for ERP considerations) antenna accessories are provided by Motorola, but other commercially available antennas may be used instead, including some with higher gain or lower loss cables. 2)For categorical exclusion of a 0.7 watt 800 MHz band radio per 47 CFR 2.1091© the antenna gain must not exceed 3.3 dBd (or equivalently, 4.3 dBq) including cable loss. None of the Motorola antenna accessories cited exceed this value, so the product and all 3 associated accessory antennas being offered qualify for categorical exclusion. Antenna cable loss for the Motorola antennas also serve to reduce antenna system gain another 1.5 to 2 dB and is not considered in the gain rating. This cable loss may differ with antenna accessories from other commercial vendors so an antenna with sufficient gain and low cable loss might not qualify for categorical exclusion. Attached per your request is MPE evaluation data obtained in several mounting positions at a separation distance of 20 cm for the 3 categorically excluded Motorola, Inc. antenna accessories cited. The maximum power density measured, as stated in paragraph 3.0, was 0.021 mW/cm 2 . This is about 3.9% of the general population Maximum Permitted Exposure (MPE) limit specified in table 1B in 47 CFR 1.1310. We trust this adequately provides the information you requested.

FCC ID: AZ489FT5797 www.mot.com/iDEN iDEN, Motorola Inc., 8000 W. Sunrise Blvd., Plantation, FL 33322 Date: December 17, 1999 Mr. Frank Coperich Authorization & Evaluation Division Federal Communications Commission Laboratory 7435 Oakland Mills Road Columbia, MD 21046 Dear Mr. Coperich; Motorola Inc., 8000 West Sunrise Boulevard, Fort Lauderdale, Florida 33322, herein submits it’s response to the December 17 request for information on FCC ID: AZ489FT5797, EA95186 via correspondence number 11076. 1) This device is a “data only Mobile Transceiver”, as noted in Exhibit 13-1 cover letter. Thus, we do not require the D7E emission designator for QAM voice mode, as recommended by the Commission. 2) We accept that the FCC’s recommendation that the 4-QPSK data mode is covered by DXW. Please amend the form 731 and the application to reflect Emission Designator 18K3DXW. 3) In the data mode the radio subchannels may use 16-QAM or 64-QAM modulation as alternatives to 4-QPSK as clarified in Exhibit 6.2 which accompanied our application. Given the use of D as the first symbol for the class of emission, and since the modulation filter is the same for all three modulation methods, we trust that 18K3DXW would be applicable to those as well. 4) The necessary bandwidth calculation was included in Exhibit 6.2 which accompanied our application. We are listing it below for reference. “... the necessary bandwidth of these subchannels is limited to 4.8 kHz by the pair of modulation low pass filters. The transfer response of these filters is depicted in Figure 6-1 where the filter excess bandwidth coefficient of 0.2 is shown. This excess bandwidth leads to the necessary bandwidth calculation of (1 + 0.2) x (4 kHz) = 4.8 kHz. Since the sub-channels are spaced 4.5 kHz apart, the necessary bandwidth of the composite 4 sub-channel symbol streams is 4.8 + (3 x 4.5) = 18.3 kHz.” We trust this adequately provides the information you requested. Please contact me at (954) 723- 5793 if you require any additional information. Sincerely, Mike Ramnath FCC ID: AZ489FT5797 www.mot.com/iDEN iDEN, Motorola Inc., 8000 W.

In almost all vehicles, these requirements are best satisfied by mounting the antenna at the center of the roof. Some vehicles have a large trunk lid that provides a good antenna location. If the trunk lid is used, connect grounding straps between the trunk lid and vehicle chassis to ensure the trunk lid is at chassis ground. Three types of antennas can be used: 1. RAFU136A - Magnetic Antenna 2. FAD5524A - Mobile Window Antenna 3. HAF9067A - Mobile Roof Mount Antenna Antennas with gain exceeding 3 dBd do not comply with FCC RF exposure regulations and are not allowed for use with this product. Make sure that you refer to the antenna installation instructions according to the kit number”. Also, page 96 of the User’s Manual for Antenna and Installation Considerations, is listed below for your reference: Antenna and Installation Considerations “ All equipment must be properly installed in accordance with Motorola installation instructions.  To assure compliance with United States FCC regulations on RF exposure, the user of the equipment must position the antenna in such a way to maintain a separation of at least 8 inches (20 cms) between the antenna and the body of any user and nearby person.  Ensure that the antenna is properly installed external to the vehicle FCC ID: AZ489FT5797 www.mot.com/iDEN iDEN, Motorola Inc., 8000 W. Sunrise Blvd., Plantation, FL 33322 and in accordance with the requirements of the antenna manufacturer/supplier.  Use only the supplied or an approved antenna. Unauthorized antennas, modifications, or attachments could impair call quality, damage the modem, or result in violation of the ICNRP or the FCC”. 2)We are in agreement with the Commission’s proposed grant condition that “Antennas for this device must be vehicle mounted to provide at least 20 cm separation between the antenna and persons for satisfying MPE requirements. MPE tested with 3 dBd antennas, use of other antennas must not exceed total system output of 1.5 W ERP. The appropriate information for satisfying RF exposure compliance must be provide to installers and end users”. We trust this adequately provides the information you requested.

Transmitter Description -----47 CFR. 2.1033 (c) 4,5,6,7,8 12.1.Transmitter Technical Characteristics This trunked radio transceiver is of the receive first type, meaning it must first find, acquire and lock onto a control channel from a predefined set of control frequencies assigned to a compatible base station. Transmission is not possible until acquisition and lock has been achieved, then it is limited to transmission of service request bursts on the digitally modulated reverse control channel. Upon recognition of a proper request, the control channel base station transmitter will then assign the transceiver a traffic channel for transmission of digital circuit switched or packet switched data from the set of frequencies for which the trunking system is licensed. In addition to controlling the assigned frequency to which the transceiver will be slaved, the base station frequency serves as an accurate, stable reference for the transceiver local reference oscillator by virtue of an AFC function inherent in the acquisition and lock process. The base station allocates the number of 15ms time division multiplex (TDM) time slots in which the transceiver transmits, depending on the user requested transmission mode. The trunking system protocol for data transmission uses a 90ms frame divided into six 15 ms time slots. These slot allocations are summarized in Table 12.1 below. Transmission ModeTime Slots Allocated Per FrameDuty Cycle 1:6 Circuit Switched Data Mode116.67% 1:3 Circuit Switched Data Mode233.33% Packet Data Mode up to 81 of 120 slotsup to 67.5% Table 12.1: Time Slot Allocation Table RF Power Output Transmitter output power may be automatically attenuated by up to 24 dB below the maximum transmitter output power setting upon receipt of a command signal from the base station to prevent base station receiver overload. The user has no control over this setting.
