FCC ID:ALH29383230(TK-860HGK3) FCC ID:ALH29383230(TK-862HGK3) 1 TK-860HG Circuit Descriptions The Kenwood model TK-860HG is an all solid-state frequency synthesized UHF/FM transceiver designed for operation in the frequency range of 400MHz to 430MHz (ALH29383230).TK-860HG is 128 Number of channels, and TK-862HG is 8 Number of channels. The unit consists of a TX-RX unit and LCD assembly and its transmitter is rated for 40W output power . 1. TX-RX Unit The TX-RX unit consists of a Voltage Control Oscillator (VCO) sub-unit, a receiver section, a transmitter section, a control section and a power supply section. 1.1 PLL Frequency Synthesizer The transmit signal and the receiver first L. O. signal are generated by the PLL digital frequency synthesizer. The frequency synthesizer consists of a transmitter voltage controlled oscillator (TX VCO, Q103), a receiver voltage controlled oscillator (RX VCO, Q101), a buffer amplifier (Q106), an RF amplifier (Q9), a low-pass filter, a PLL IC (IC3) and TX VCO/RX VCO switches (Q104 and Q105). In the transmit signal mode, an operating frequency programming data is sent to IC3,from the control unit, to set the programmable counter within IC3. Q104 is turned on to activate the TX VCO and the output signal of the TX VCO is amplified by Q106 and Q9 before it is routed to IC3. The signal is then divided down in frequency, at the programmable counter in IC3, to 5.0kHz or 6.25kHz which is compared in phase with a 5.0kHz or 6.25kHz reference signal, derived from 16.8MHz crystal oscillator and a 1/3360 or a 1/2688 fixed counter in IC3, at the phase comparator also in IC3. The crystal oscillator operates at 16.8MHz and its frequency stability is maintained within 2.5ppm (temperature range of –30 to +60
) . The phase comparator output signal is fed into a low-pass filter before being applied to the TX VCO as a frequency control voltage. If an unlock condition occurs in the phase locked loop, this condition is detected by D9. This cause the transmitter 8V supply cut off, resulting the prevention of an unauthorized transmission. The transmitter modulation signals (processed Mic. audio and sub-audible signaling) are applied to the TX VCO for frequency modulation. In the receive mode, the VCO is substituted with Q101 (RX VCO) and it generates the receiver first local oscillator signal according to the data sent from the control unit. The basic operation of the synthesizer remains the same. FCC ID:ALH29383230(TK-860HGK3) FCC ID:ALH29383230(TK-862HGK3) 2 1.2 Receiver Circuit The receiver is a double conversion super-heterodyne, designed to operate in the frequency range of 400MHz to 430MHz (ALH29383230). The receiver RF and IF sections consist of an RF amplifier (Q34), a first mixer (Q15), and an FM IF IC (IC5). An incoming RF signal from the antenna is fed into a band-pass filter which consists of L22 and variable capacitors (D28 and D31) after going through an antenna switch in the transmitter power amplifier section. The D28 and D31 will be electrically tuned by TV voltage for the best BPF response. This RF signal is then amplified by an RF amplifier (Q34) and filtered again by band-pass filters ( L13 and D18, D23 ). After amplification and filtering, the signal is applied to the first mixer (Q15) for mixing with the first local oscillator signal generated by the frequency synthesizer. The heterodyning action of the first mixer produces a 49.950MHz intermediate frequency (first IF), which is applied into two monolithic crystal filters. The signal out of the crystal filters is amplified by a first IF amplifier (Q13) and is sent to the FM IF IC (IC5). The FM IF IC (IC5) contains a second mixer, a second local oscillator, second IF amplifiers, a second IF filter, an FM detector and a RSSI output. The signal applied to IC5 is mixed with 50.400MHz, which produces a 450kHz second IF signal. The signal obtained at the second mixer is filtered by a 450kHz ceramic filter (CF1 for narrow or CF2 for wide) and it is amplified by limiting amplifiers. The recovered audio signal from the incoming signal is obtained from quadrature type FM demodulator. This recovered audio signal is then sent to the audio amplifier circuit and to the noise actuated squelch circuit. The recovered audio signal obtained at IC5 is de-emphasized and further amplified for driving a loud speaker. 1.3 Transmitter Circuit The transmitter circuit consists of a microphone amplifier, an RF power amplifier driver (Q22,Q25 and Q27), an RF power amplifier module (IC400), an antenna switching network, a spurious and harmonics low-pass filter, and an automatic power control (APC). The audio signal, originating at the microphone, is applied to the microphone amplifier (IC507, IC508). The audio signal is amplified, pre-emphasized (IC508), voltage limited and low-pass filtered. The signal is then switched by transistors to the TX VCO for modulating the transmit carrier signal or to public address operation. The transmit signal, generated at the frequency synthesizer, is applied to the RF power amplifier driver to gain a sufficient signal level to drive the RF power amplifier. FCC ID:ALH29383230(TK-860HGK3) FCC ID:ALH29383230(TK-862HGK3) 3 The output signal from the RF power amplifier driver is further amplified, in the RF power amplifier module, up to the level of the transmitter rated output power. This signal is routed to the antenna connector after going through the antenna switching network and the low-pass filter. This filter has a minimum attenuation of 65dB at the second harmonic frequency. This output power level once it was set it will be maintained at a constant output level by automatic power control unit (D35, D36, IC15, Q31and Q32). 1.4 Control Section The control section consists of a CPU (IC502), LCD unit and associated interface circuits. The CPU (IC502) is connected to an external EEPROM (IC505), which stores the operating frequency information. The CPU (IC502) performs the following functions: (1) Switche…

FCC ID: ALH29383230 MFA p0090004, d00a0066 PAGE NO.4of6. 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. FCC ID: ALH29383230 MFA p0090004, d00a0066 PAGE NO.5of6. 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 from the formula Power Density = EIRP / 4πR 2 …
