MOTOROLA INC.FCC ID: ABZ99FT3003 EXHIBIT 5 CIRCUIT DESCRIPTION A general description of the overall circuit is covered in the instruction manual. This section provides the description of circuits required by subpart 2.983 of the Commissions’ rules. Circuits not described in the manual are covered in this exhibit. This exhibit contains descriptions of the frequency generation, modulation and transmitter circuits in accordance with FCC Rules Part 2.983(d). The following descriptions are included: EXHIBIT 5A - Means for Frequency Stabilization, 2.983 (d) 10 EXHIBIT 5B - Means for Limiting Modulation and Attenuation of Higher Audio Frequencies, 2.983 (d) 11 EXHIBIT 5C - Means for Attenuation of Spurious Emissions, 2.983 (d) 11 EXHIBIT 5D - Means for Limiting Power Output, 2.983 (d) 11 EXHIBIT 5E - Modulation Techniques, 2.983 (d) 12 MOTOROLA INC.FCC ID: ABZ99FT3003 EXHIBIT 5A MEANS FOR FREQUENCY STABILIZATION Circuit Description: A 16.8 MHz Temperature Controlled Crystal Oscillator (TCXO), U5700 (a “Pendulum” oscillator), maintains frequency stability of the transmitted carrier. The TCXO features low current drain and a ±1.5- ppm frequency versus temperature capability. In addition, this TCXO offers digital tuning and a temperature referenced 5 bit Digital to Analog Converter (DAC). Frequency tuning has 128 steps of resolution. The 16.8 MHz output frequency of the TCXO is divided into one of three reference frequencies in the fractional-N frequency synthesizer IC, U5702. These reference frequencies are compared to the divided outputs of the VCOs in a phase detector. The output of the phase detector provides a DC correction voltage back to the VCOs. The carrier frequency for conventional operation, in the range of 806 to 821 MHz, is generated using a Bipolar Transistor, Q5706, configured as a voltage controlled oscillator (VCO). The Q5706 VCO also supplies the injection power for the first mixer of the receiver. The carrier frequency for talk-around operation, in the range of 851 to 866 MHz, is generated using a Bipolar Transistor, Q5704, configured as a voltage controlled oscillator (VCO). Only one VCO is operating during transmissions. The output of one or the other of the VCOs is applied to the input of fractional-N, frequency synthesizer integrated circuit, U5702. U5702 consists of a phase-locked loop circuit with the output of the VCOs fed to a programmable divider chain. The divide ratios are determined from information stored in the Electrically Erasable Programmable Read Only Memory (EEPROM) in the microcomputer, U0101, and bussed to the synthesizer. The microcomputer extracts the data for the division ratios as determined by the mode (channel) of operation selected. Using a time averaged algorithm a combination of divide ratios is used so that the reference frequency can be a much higher value than the value of the frequency resolution. Modulation occurs by a combination of directly coupling the modulation signal to the low pass filter in the loop and by processing the modulation signal to alter the divider values. A block diagram of the VCO/Synthesizer system is shown in Figure 5.1. Figure 5.1 – Carrier Frequency Generation and Stabilization MOTOROLA INC.FCC ID: ABZ99FT3003 EXHIBIT 5B MEANS FOR LIMITING MODULATION AND ATTENUATION OF HIGHER AUDIO FREQUENCIES Circuit Description: Modulation limiting is accomplished within the custom audio processor IC, U0201 (“ASFIC”). The limiting action itself occurs at the rails (i.e., 5V and ground). Using an operational amplifier with feedback, very hard limiting is obtained. The limited modulation signal output of the limiter is applied to a low-pass filter in U0201. The filter is a fifth-order, Butterworth switched capacitor filter with the 3-dB roll-off corner frequency located at 3250 Hz. The output of the low-pass filter is applied to the input of the electronic attenuator. The electronic attenuator is controlled by the microcomputer of the transceiver. To keep the deviation constant over the RF frequency range, the microcomputer adds the proper correction factor to the attenuator. A block diagram of the limiting and low pass filtering is shown in figure 5.2. Figure 5.2 – Transmitter Modulation Limiting and Lowpass Filtering MOTOROLA INC.FCC ID: ABZ99FT3003 EXHIBIT 5C MEANS FOR ATTENUATION OF SPURIOUS EMISSIONS Circuit Description: The final stage of the RF power amplifier circuit feeds a low-pass filter in order to attenuate harmonics of the output frequency as well as spurious outputs. The filter is a seventh-order, 0.1 dB Chebychev design using LC reactive elements. Shielding of the transmitter RF power amplifier circuit also attenuates spurious emissions. The circuit diagram may be found in Figure 5.3.

The forward power detector is placed after the harmonic filter and before the antenna connector. The forward power detector is a microstrip printed circuit, directional coupler. A sample of the forward energy is rectified by CR6506 to produce a dc voltage proportional to the output power of the transmitter. That voltage is applied to the Power Control IC, U1503, and is compared to a preprogrammed voltage reference. Any difference between the two inputs generates an error voltage. The error voltage is amplified and the resulting output from the power control is used as a bias control voltage for the first transmitter stage, Q6501. The bias control voltage changes the gain of Q6501 to maintain constant dc voltage from the power detector and, therefore, transmitter output power. The voltage drop across current sensing resistor R6520 is proportional to the collector current of the final power amplifier transistor, Q6505. The volta…

Re:FCC ID ABZ99FT3003 Applicant:Motorola, Inc. Correspondence Reference Number: 13461 731 Confirmation Number:EA96210 Date of Original E-mail:2000 April 14 Date of Response:2000 May 19 Mr. Error Chang: In response to your inquiries in your e-mail dated 2000 April 14, Motorola, Inc. submits the following answers and clarifications. Your questions are repeated here, in quotation marks, to provide continuity. “1. The MPE report indicated tests were performed at 20 cm from the side of the vehicle and 60 cm from the back of the vehicle for the antenna configurations evaluated. Normally measurements should be made at the closest distance persons may normally be from the antenna so that the proper distance can be used in the installation procedures without imposing any burden on the radio operator to maintain the additionally needed separation distance as indicated in the manual.” For clarification the test lab procedures prescribe fixed distances to the antenna of 30, 60, or 90 cm depending on the transmitter power output and consistent with the distance instructions in both the User Manual and the Installation Manuals. One additional prescribed procedural item is to not allow the probe to be closer than 20 cm from the vehicle body to prevent erroneous measurements per the guidance provided by ANSI/IEEE C95.1, Section 6.6. Hence t he measurements made for this nominal 35 watt radio were conducted at a distance of 20 cm from the side of the vehicle for a roof center mount antenna and 60 cm from the antenna for a center trunk mount antenna. “Please clarify with respect to the following - (a) MPE report indicated this radio was evaluated for controlled/occupational exposure environment. Please confirm if marketing of this radio will be limited to occupational workers who will be trained and have knowledge to control the exposure conditions for all persons exposed to the antenna of this radio and maintaining the needed distance proposed in the manual (2 feet from the vehicle) to ensure RF exposure compliance. If so, please clarify how such training will be implemented so that additional clarifications will be unnecessary for satisfying uncontrolled MPE limits.” This device is designed specifically for use by occupational workers (occupational/ controlled environment) and will be marketed to federal gover nment and public safety agencies and private businesses such as utilities, airlines and railroads. These radios are typically used in a disciplined way to help improve productivity, control and coordinate work teams, and enhance personal safety. Push-to-talk two-way radio conversations are measured in seconds, not minutes. The user's manual provides clear instructions on proper usage, including a specific section on EME. As a point of clarification the user instructions relative to distance are referenced to the antenna and not to the vehicle. While user training is the responsibility of the customer, who uses manuals, instructional sessions or other means to inform workers, Motorola also offers its customers training classes on the proper use of two-way radios. “(b) If the radio is not intended for use in occupational environment that requires workers to have the needed knowledge to qualify for the higher controlled MPE limits, please clarify and/or provide additional data to indicate exposure at the side of the vehicle, closest to the antenna configurations, can comply with uncontrolled MPE limit. Note: the roof center antenna w hen mounted on the left or right side of the trunk edge, as suggested in the manual, would represent worst case.” As noted above the radio is intended for use in the occupational environment. The Antenna manual contained in Exhibit 12D is a generic manual for a series of 12 different antennas that are selectively specified by a variety of different radio models. The User Manual for this radio specifies only one of the twelve antennas, the HAF4002A; i.e. the Trunk Lip Mount antenna is not specified for this radio. “2. If necessary, the relevant installation and user information should be revised accordingly.” The manual previously uploaded as Exhibit 12D has been modified to add the following note for the Trunk Lip Antenna Models: "Not recommended for transmitters with power output 7 watts or greater" New versions of the Radio, the Mobile ¼-Wavelength Antennas and the Mobile Gain Antennas installation manuals are provided as replacements for Exhibit 12C, Exhibit 12D and Exhibit 12E, respectively.
