FCC ID:ALH31113130 TKR-850 K3 Circuit Description The KENWOOD model TKR-850 K3 is a UHF/FM relay radio designed to operate in the frequency range of 400 to 430MHz. 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 400MHz to 430MHz. The receiver circuit located in TX-RX unit (X57-627A/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 F3: 400.000 to 430.000MHz and the spread is 3.0MHz. 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:ALH31113130 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), and consists of…

FCC ID:ALH31113130(TKR-850K3) TKR-850 K3 Tuning procedure Before attempting to tune the transceiver, connect the unit to a suitable power supply. Whenever the transmitter tuned, unit must be connected to a suitable dummy load, unless the instruction specify otherwise. The speaker output connector must be terminated with a 4 Ohm dummy load at any time during the tuning and connected to an AC voltmeter and an audio distortion meter or a SINAD measurement at all the time during the tuning. Turn the power switch on when connect to PC and FPU cable (KPG-46) with Radio. Start up the FPU (KPG-66D). Select to "Program – Test-Mode" from the menu bar at the FPU window, or press the CTRL-T , then select "Test Mode" and open the "Test Mode" window. (1) Manual Tuning The Manual Tuning needs to be done before PC tuning. The items are as follows; 1. RX VCO lock voltage, 2. BPF adjustment, 3. MCF adjustment, 4. Discriminator adjustment, 5. TX VCO lock voltage. These adjustment parts (L2/L4/L5/ L14/ L15/L16/ L17/L18/ L19/L24) and connectors (CN1/CN2/CN4) are on TX/RX unit (X57-627* A/2). 1.RX VCO lock voltage a. Connect DVM (Digital Volt Meter) to “RX CV” terminal. b. Adjust the PLL lock voltage with TC350/351 at the VCO unit (X58-480*). 2.BPF adjustment a. Connect the TG (tracking generator) to RX IN connector on the rear panel. b. Connect CN1 to the spectrum analyzer input. c. Adjust L2/L4/L5, and obtain the correct waveform at the desired frequency. 3.MCF adjustment a. Connect the TG to CN2, then connect CN4 to the spectrum analyzer input. b. Adjust L14/L17/L18 in the wide mode, and obtain the correct waveform at the desired frequency (44.85MHz). c. Adjust L15/L16/L19 in the narrow mode, and obtain the correct waveform at the desired frequency (44.85MHz). 4.Discriminator adjustment a. Connect the SSG to the RX IN connector. b. Input desired RF signal with standard modulation. c. Adjust L24 until obtain the maximum AF level. 5.TX VCO lock voltage a. Connect DVM to “TX CV” terminal. b.
