AXATR-390-A2Trunking Mobile Radio

 KME 800 Instruction Draft 1, Receiver Circuit The FM dual-conversion super heterodyne receiver is designed for operation in the 851-870MHz frequency range. The Receiver has intermediate frequencies (IF) of 82.2MHz and 455KHz. Adjacent channel selectivity is obtained by using two band pass filters, a 82.2MHz crystal filter and a 455KHz ceramic filter. The FM-detector is Quadrature discriminator. 1-1 Receiver Front-end A RF signal from antenna is coupled though the low pass filters, antenna switch and band pass filter to the input of low noise amplifier TR201. The output of TR201 is coupled through band pass filter to input of 1’st Mixer TR203. Front End selectivity is provided by these band pass filter. 1-2 1’st Mixer The 1’st Mixer is a Transistor-Mixer (TR203), that converts a RF signal the 851-870MHz range to 82.2MHz 1’st IF frequency. In the mixer stage, A RF signal from the Front-end RF filter is applied to the input of the Transistor-Mixer. 1-3 1’st IF The 82.2MHz 1’st IF output signal is coupled from the output of T201 through IF amplifier TR204 and Crystal filter FL201 to IF-amplifier TR205. The highly-selective crystal filters FL201-1 and FL 201-2 provide the first portion of the receiver IF selectivity. The out put of the filters is coupled through the impedance-matching net work T204, C246 and R224 to 1’st IF amplifier TR205. 1-4 2’nd Mixer, 2’nd IF filter,2’nd IF amplifier and FM detector IC201 is an one-chip IC for FM communication system. It includes 2’nd Mixer, 2’nd IF amplifier and FM detector. The 2’nd Mixer is a Balanced Mixer, that converts a 1’st IF signal 82.2MHz range to 455KHz 2’nd IF frequency. The 2’nd IF signal is applied to Ceramic Filter FL203, which provides the 455KHz selectivity. The output of the 2’nd IF filter is applied to 2’nd IF amplifier in IC201. The 2’nd IF signal is then amplified, filtered and limited. Discriminator (DSC201) shifts the 2’nd IF signal by 90deg and applies it to the internal FM detector. The FM detector compares the shifted IF signal to the internal IF signal to recover the audio modulation. The audio output of IC201 is applied to audio amplifier buffer IC205-2. The audio output of IC205-2 is then applied to the SYSTEM CONTROL UNIT. 2, Transmitter Circuit The Transmitter Circuit consists of one Class-A Amplifier TR101, Pre-Driver IC101, PA Module IC102, RF Amplifier TR102, Automatic Power Control Circuit (TR105- TR107), Antenna Switch (CD103, CD105- CD107 and CD109), Low Pass Filter (Micro Strip Line and C146-C153, C181 and C183). 2-1 Class-A Amplifier The 806-825MHz and 851-870MHz RF input from Synthesizer output of TR316 is applied to the band pass filter FL301 through an attenuator pad R301-R303. RF input level is about +3dBm, that is amplified to +10dBm by TR101. This is controlled by TXENB+.  2-2 Pre-Driver The output of TR101 is applied to the Pre-Driver IC101 through an attenuator pad R106-R108. The output of R107 is also amplified to about 600mW by IC101. This is controlled by TXENB+. The Pre-Driver consists of three stages RF amplifier. The first and second stages in IC101 are operated in Class-B. The third stage in IC101 is operated in Class-C. 2-3 PA Module The output of IC101 is applied to the PA Module IC102 through an attenuator pad R110-R112. The output of R110 is amplified to about 13W. The PA Module consists of three stages RF amplifier. The first stage power supply voltage is controlled by power control circuit. The second and third stage power supply voltages are supplied by B_A+ via TR108. The first and second RF amplifiers are operated in Class-B. The third RF amplifier is operated in Class-C. 2-4 RF Amplifier The input (about 13W) of the RF Amplifier is amplified to 25W. Power Supply voltage for the RF Amplifier is connected with POWER SUPPLY BOARD through C1. 2-4 Automatic Power Control The Automatic Power Control circuit samples the output power to the antenna to maintain a constant power level across the band. Also, a thermistor circuit (TR104 and RT101) senses the PA Module temperature to reduce the power level when the temperature is above +110 °C. The Automatic Power Control circuit controls the supply voltage to the first stage in PA Module IC102. Directional coupler provides a sample of transmit power for diode CD102. Diode CD102 produce a positive DC voltage proportional to the transmit circuit output power level. When above VSWR 3, reflect coupler provides a sample of reflection power for diode CD101. Diode CD101 and CD102 produce voltages are summed, then that is compared to APCREF (D/A Voltage) from SYSTEM CONTROL UNIT by the amplifier TR105. The collector of TR105 is applied to DC amplifier TR106 and TR107, then the output voltage of TR107 controls to the first stage of PA Module. 2-5 Antenna Switch and Low Pass Filter The Antenna Switch consists of CD103, CD105-CD107, CD109 and the Low Pass Filter consists of micro strip line and C146-C153,C181 and C183. During transmit, TXENB+ line from SYSTEM CONTROL UNIT is high level. Transistor TR109 turns on supply +9VT to the Class-A Amplifier and Pre-Driver, Automatic Power Control circuit and PIN diode Antenna Switch CD103, CD105-CD107 and CD109. When transmitting, the Antenna Switch diode is low impedance. 3, Frequency Synthesizer Circuit The Frequency Synthesizer circuit receives PLL data, and control information from the microcomputer and from this generates the Tx / Rx RF frequencies. It also provides frequency lock status to SYSTEM CONTROL UNIT. It consist of the Reference Oscillator, PLL Frequency Synthesizer chip IC305, Loop filter, Rx VCO TR307, Tx VCO TR304, Feedback Buffer Amplifier, and Dual-Modulus Prescaler IC306. Rx VCO and Tx VCO are locked to the Reference Oscillator by a single direct-divide synthesis loop consisting of the Feedback Buffer, Prescaler, and PLL Frequency Synthesizer chip. The Tx VCO operates over a frequency range of 403-412.5MHz and 425.5-435MHz. The Rx VCO operates over a frequency range of 384.4-393.9MHz.  3-1 Refer…

AXATR-390-A2 ERICSSON INC CIRCUIT AND DEVICE DESCRIPTION (10) Oscillator and other Frequency Stabilizing Circuit Descriptions: The frequency reference is a self-contained quartz crystal oscillator (TCXO) module, operating 12.8MHz. The TCXO is compensated by internal temperature compensating circuit providing 1.5PPM stability from -30 °C to +60°C. (11) a. b. c. d. e. f. Circuit or devices employed for suppression of spurious radiation: The radio has metal cover and metal cabinet. Extensive use of discrete bypass capacitors in the Option and Remot e Control Connector of the radio reduces radiation from remote cables. Low pass harmonic filter follows power amplifier output. Internal shields surround synthesizer, power amplifier and System Control logic circuitry. In addition the Control Unit package is metallized to suppress microprocessor radiation. During acquisition of the synthesizer phase lock loop, the transmitter output is inhibited by an RF gate and the removal of DC voltage to the gain control stage of the RF power chain. (12) a. b. Circuit or Devices employed for limiting modulation: Reference is made to the schematic diagram XD00-TC-0099 in Exhibit 4. Instantaneous audio limiting is accomplished Audio IC (IC501). The Audio IC provides both limiting and Post-Limiting filtering. The Audio IC runs from a regulated supply voltage, which prevents deviation changes vs. changes in radio power supply voltage. Following the Limiter, a summing amplifier is used to add in any optional tone modulation, such as CTCSS and CDCSS modulation, which is also temperature and voltage stable. The output from the summing amplifier then passes through the post- limiting filter to a modulation level adjust liner attenuator (also contain IC501), which is in turn coupled to the FM modulated oscillators. The attenuator insures maximum deviation + 4.5KHz. Exhibit 10 APPLICANT: FCC ID NO. AXATR-390-A2 ERICSSON INC CIRCUIT AND DEVICE DESCRIPTIO (13) a. b. c. d. e. f.

The following measurements were performed with a Narda probe using ANSI/IEEE C95.1 as a guide. 2. Prior to making any measurements, the measurements system was calibrated in accordance with the manufacturer’s procedures. 3. The EUT’s radiating element (antenna) was placed on a 1 m tall table for ease of testing. For equipment normally operated on a metal surface, a ground plane was used. 4. The remaining equipment necessary to operate the EUT was maintained at a distance from the measurement arrangement suitable to minimize interference with the measurements. 5. The minimum safe distance was calculated from the formula Power Density = EIRP / 4πR 2 (Peak Watts/m 2 ). The calculation is shown with the measurement data. 6. With the EUT operating at maximum power, a search was initiated for worst case emissions with the probe raised and lowered over a range of 0.2 to 2 meters in height and over a horizontal plane of 0 o to 360 o . 7. Average values were calculated for the whole body (0.2-2.0m), lower body (0.2-0.8m) and upper body (1.0-2.0m). Results:Attached. FCC ID: AXATR-390-A2 MFA p9990013, d9990049 PAGE NO.6 of 10.

KME 800 Antenna InstallationRev PA710/22/99W. W. Hays III Antenna – 19B209568P5 Installation instructions for the antenna are packaged with the antenna. The antenna must be assembled and installed in accordance with the accompanying manufacturer's instructions and applicable industry standards for optimum results and safety. The antenna should be located in the center of the roof or center of rear deck (i.e. trunk lid). Some states have laws governing restriction of visibility of vehicle operators by added items, such as antennas. Be familiar with local laws and locate antennas accordingly. Route the cable away from locations where it will be exposed to heat, sharp edges or mechanical damage, and where it will be out of the way of the driver, passengers or vehicle mechanics. Wherever possible, existing holes in the trunk wall, and the channels above or beneath doors and window columns should be utilized. Avoid routing the antenna cable near any electronic modules or along side any vehicle wiring. Connect the antenna TNC cable connector to the TNC connector on the radio, being careful not to twist the cable. Maximum Permissible Exposure (MPE) In August, 1996, the FCC adopted an updated safety standard for human exposure to RF electromagnetic energy emitted by FCC-regulated equipment. Ericsson PRS subscribes to this same updated safety standard for the use of its radio products. Mobile or Fixed Station Operation The antenna specified above is a ¼-wave, monopole, unity-gain (2.15 dBi), omni- directional antenna. It is the only 800 MHz antenna offered for sale by Ericsson for use with the EDACS 500M radio. MPE has been evaluated with this antenna, only, in combination with the EDACS 500M. These evaluations indicate that the FCC limits of Maximum Permissible Exposure (MPE) for General Population/Uncontrolled Exposure, as specified in 47 CFR § 1.1310, are not exceeded at distances of more than 31 inches (78 cm) from the antenna axis, when mounted in accordance with the prescribed procedure and locations. Substitute Antennas different from the above indicated performance. CONSULT THE SUPPLIER OR MANUFACTURER FOR INSTRUCTIONS BEFORE MAKING ANTENNA SUBSTITUTIONS. RADIO OPERATOR WARNING Operators of this radio and antenna combination must not transmit when persons are within the MPE radius [31 inches (78 cm)] of the antenna, unless such persons (e.g. the operator) are isolated from the antenna field by a grounded metallic barrier (e.g. the user's vehicle rooftop). FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS THE SPECIFIED MPE LIMIT.
