FCC ID:ALH31113110(TKR-850K) TKR-850 Circuit Description The KENWOOD model TKR-850 is a UHF/FM relay radio designed to operate in the frequency range of 450 to 480MHz. The unit consists of receiver, transmitter, phase-locked loop (PLL) frequency synthesizer, and control circuits. 1. RECEIVER CIRCUIT The receiver is double conversion super-heterodyne, designed to operate in the frequency range of 450MHz to 480MHz. The receiver circuit located in TX-RX unit (X57-627 A/2) consists of the following: 1-1 front-end circuit, 1-2 First Mixer, 1-3 IF amplifier circuit, 1-4 audio amplifier circuit, and 1-5 squelch circuit. 1.1 FRONT-END CIRCUIT The front-end circuit consists of BPF L2, high-frequency amplifier Q1 , and BPF L4/L5 located in TX-RX unit (X57-627 A/2). The helical BPF covers frequency range F1: 450.000 to 480.000MHz and the spread is 5.0MHz. The BPF L4/L5 attenuates the unwanted out-of-band high-frequency components produced by high-frequency amplifier Q1 and unwanted components, and sends only the necessary signal to the first mixer DBM. 1.2 FIRST MIXER The signal from the BPF is heterodyned with the first local oscillator signal from the PLL frequency synthesizer circuit at the first mixer DBM(A1) to become a 44.85MHz first intermediate frequency (IF) signal. The first IF signal is fed through two monolithic crystal filters (XF2; Wide, XF1; Narrow) to further remove spurious signals. 1.3 IF AMPLIFIER The first IF signal is amplified by Q2 and Q3, and then enters IC9 (FM processing IC).The signal is heterodyned again with a second local oscillator signal(44.395MHz) with in IC9 to become a 455kHz second IF signal. The second IF signal is fed through a 455kHz ceramic filter, CF1 and CF2 to further eliminate unwanted signal, and the quadrature detection circuit FM-detects the signal to produce a base-band signal and output it from pin 11. 1.4 AUDIO AMPLIFIER The audio amplifier circuit is located in control section of TX-RX unit (X57-627 B/2). The recovered audio signal obtained from IC9 is amplified by IC608, inputted to the AINR terminal of CODEC IC (IC614), and audio processed by DSP (IC618). The processed audio signal from AOUTR terminal of IC614 is amplified by IC619(A/2) to a sufficient level, anti-aliasing filtered by IC619(B/2). The audio signal goes to an electronic volume (IC615) V3/V4, to the input of multiplexer IC (IC622), and is amplified to drive a loudspeaker by an audio power amplifier (IC629). The 4W audio output can be provided to external speaker by supplying power supply voltage 13.6V/4 ohms through the 15-pin test connector “SPO, SPG” on the rear panel. 1.5 SQUELCH CIRCUIT The output signal from IC9 enters FM IC again, then passed through a band-pass filter. The noise component output from IC9 is amplified by Q7 and rectified by D5 to produce a DC Voltage corresponding to the noise level. The DC voltage is sent to the analog port of the CPU(IC604). And IC9 outputs a DC voltage(RSSI) corresponding to the input of the IF amplifier. FCC ID:ALH31113110(TKR-850K) 2. TRANSMITTER CIRCUIT The transmitter circuit consists of the following circuits: 2-1 Microphone circuit, 2-2 Modulation level adjustment circuit, 2-3 Driver and final power amplifier circuit, and 2-4 Automatic power control circuit. 2.1 MICROPHONE CIRCUIT The signal from the microphone is passed through AGC circuit located in DISPLAY unit (X54-333), so that it dose not saturates. This circuit consists of IC501, D501, D502, Q501, and Q502. The AGC is operated by controlling the + and side levels of amplitude using the current obtained by positive and negative detection of the amplified audio signal. The audio signal goes to control section of TX-RX unit (X57-627 B/2) from DISPLAY unit(X54-333). The transmit audio signal goes to the input of the multiplexer IC(IC605) for microphone muting. The audio signal is amplified by IC610, inputted to the AINL terminal of CODEC IC (IC614), and audio processed by DSP (IC618). The processed audio signal from the AOUTL terminal of IC614 is amplified by IC616(A/2) to a sufficient level, anti-aliasing filtered by IC616(B/2), and amplified by the summing amplifier IC611 (A/2). 2.2 MODULATION LEVEL ADJUSTMENT CIRCUIT The output of the summing amplifier IC611 (A/2) is passed to an electronic volume (IC615) for maximum deviation adjustment before being applied to a varactor diode in the voltage controlled oscillator (VCO) A2 located in TX-RX unit (X57-627 A/2). 2.3 DRIVER AND FINAL POWER AMPLIFIER CIRCUITS The transmit signal is generated by the TX VCO(A2), amplified by Q11, and sent to Final unit (X45-363). This amplified signal is amplified by Q1, Q2, Q3, Q4. and this signal is passed to the FINAL stage. The RF power amplifier consists of MOS FET transistor. 2.5 AUTOMATIC POWER CONTROL, CIRCUIT AND TRANSMITTER The automatic power control (APC) circuit stabilizes the transmitter output power at a pre-determined level, and consists of forward/reflected power detector circuits, and switching transistor Q8. The forward /reflected power detector circuits detects forward RF power and reflected RF power to DC voltage, and consists of a CM coupling type detection circuit formed by a strip line, RF detector D4/D5, and DC amplifier IC3(A/2). The voltage comparator (IC3 B/2) compares the voltage obtained by the above detected voltage with a reference voltage, set using the microprocessor and IC6 located in the TX/RX unit. An APC voltage proportional to the difference between the sensed voltage and the reference voltage appears at the output of IC1. This output voltage controls the gate voltage for the drive amplifier Q4 and final amplifier Q5, which keeps the transmitter output power constant. 3. PLL FREQUENCY SYNTHESIZER The PLL frequency synthesizer circuit consists of the following circuits: 3-1 Receiver PLL circuit, 3-2 Transmitter PLL circuit, and 3-4 unlocked detector circuit. 3.1 RECEIVER PLL The receiver PLL circuit is located in VCO unit A3 (X58-480) on TX-RX unit (X57-627 A/2), …

STANDARD TEST CONDITIONS and ENGINEERING PRACTICES Except as noted herein, the following conditions and procedures were observed during the testing: In accordance with ANSI C63.4-1992/2000, section 6.1.9, and unless otherwise indicated in the specific measurement results, the ambient temperature of the actual EUT was maintained within the range of 10°to 40°C (50°to 104°F) unless the particular equipment requirements specify testing over a different temperature range. Also, unless otherwise indicated, the humidity levels were in the range of 10% to 90% relative humidity. Prior to testing, the EUT was tuned up in accordance with the manufacturer's alignment procedures. All external gain controls were maintained at the position of maximum and/or optimum gain throughout the testing. Measurement results, unless otherwise noted, are worst case measurements.

Name of test:Environmental Assessment Specification:FCC: 47 CFR 1.1310 Measurement Guide:ANSI/IEEE C95.1 1992 Test Equipment:Maximum Permissible Exposure (MPE) measurement system, consisting of: Narda 8717-1174R, Radiation meter Narda 8761D, E-field probe (300 kHz – 3 GHz) (Calibrated Nov-98) Measurement Procedure: 1. 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 ona1mtall 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. The calculation is shown with the measurement data. 6. With the EUT operating at maximum power, a…
