DESCRIPTION OF CIRCUITRY RULE PART NUMBER:2.983 (d)(10) THEORY OF OPERATION 1.0PURPOSE This report has been prepared to support the application for FCC Type Acceptance PER CODE OF FEDERAL REGULATIONS, TITLE 47, PARTS 2, 90 AND 101 for the transmitter subsystem of the JDT Model 242-3492-XYZ Transceiver. The report presents necessary information concerning electrical circuit description, measured performance and physical construction and configuration. 2.0DL-3492 TRANSCEIVER 2.1GENERAL The main subassemblies of this transceiver include the RF board, and Modem board. The RF board provides frequency modulation and demodulation of the radio frequency signal. The main components of the RF board include the Frequency Synthesizer/VCO, dual conversion superheterodyne receiver, RF exciter/power amplifier, and a Temperature compensated crystal oscillator as a frequency reference. The main components of the modem board include the microprocessor, transmit audio processing circuitry, and receive audio processing circuitry. A block diagram of the transceiver is located at the end of this section in Figure 2. 2.2TRANSCEIVER CIRCUIT DESCRIPTION The transmitter produces a nominal RF output power output of 5W at 13.3V DC. Frequency modulation of the transmit signal occurs in the synthesizer. Transmit audio processing circuitry is contained in the modem board. DRIVER (Q500) The VCO RF output signal is applied to R846, R847 and R848 that form a resistive splitter for the receive first local oscillator and the transmitter. The VCO signal is then applied to a 50 ohm pad formed by R500, R501, and R502. The RF signal is applied to Q500 which provides amplification and additional isolation between the VCO and transmitter. Biasing for this stage is provided by R503 and L500, C505 provides RF decoupling. The RF signal is then applied to the power amplifier module Q500. FINAL (U510) The RF signal from Q500 is applied to the input port of the RF power amplifier module, U510, which provides 5 watts (nominal) at the antenna connector J501. U510 operates on an input voltage from 10- 16Vdc. POWER CONTROL (U130C) Power control is provided by U520, U130, Q520 and a stripline directional coupler. The power is adjust by Power Set Control R525 which provides a reference voltage to U130C. U130C drives Q520 and PA module U510. The stripline directional coupler is connected to a forward RF peak detector formed by R535, CR520, C531 and U520A. The other end of the stripline directional coupler is connected to a reverse RF peak detector formed by R593, CR592, C593 and U520B. If the power output of U510 decreases due to temperature variations, etc., the forward peak detector voltage decreases. The detector voltage drop is buffered by U520A and applied to inverting amplifier U130C which increases the forward bias on Q520. The increased bias voltage on Q520 increases the power output level of U510. If the power output of U510 increases, the forward peak detector voltage increases and U130C decreases the forward bias on Q520. The decreased bias voltage on Q520 decreases the output power of U510. The output of CR520 and CR592 are applied to U520. If the output of either buffer increases, the increase is applied to the inverting input of U130C. The output of U130C then decreases and Q520 decreases the input voltage to U510 to lower the power. The control voltage is isolated from RF by ferrite bead EP513 and C513 decouples RF. The forward/reverse power voltages from U520A/B are also applied to U913/U912 for outputs on J201. LOW PASS FILTER The low-pass filter consists of L540, C541, L541, C542, L542, C543, and C544. The filter attenuates spurious frequencies occurring above the transmit frequency band. The transmit signal is then fed through the antenna switch to antenna jack J501. ANTENNA SWITCH (CR540, CR541) The antenna switching circuit switches the antenna to the receiver in the receive mode and the trans- mitter in the transmit mode. In the transmit mode, +9V is applied to L543 and current flows through diode CR540, L544, diode CR541 and R540. When a diode is forward biased, it presents a low impedance to the RF signal; conversely, when it is reverse biased (or not conducting), it presents a high impedance. Therefore, when CR540 is forward biased, the transmit signal has a low-impedance path to the antenna through coupling capacitor C546. L544, and C552 form a discrete quarter- wave line. When CR540 is forward biased, this quarter-wave line is effectively AC grounded on one end by C552. When a quarter- wave line is grounded on one end, the other end presents a high impedance to the quarter-wave frequency. This blocks the transmit signal from the receiver. C545 and C551 matches the antenna to 50 ohms in transmit and receive. TRANSMITTER KEY-UP CONTROL Q130, Q131, and Q132 act as switches which turn on with the RX_EN line. When the line goes low Q130 is turned off which turns Q131 on turning Q132 on. This applies 13.3V to U130 before the TX_EN line goes high. U130A/B provides the key-up and key-down conditioning circuit. C116 and R117 provide a ramp up and ramp down of the 9.0TX during key-up and key-down which reduces load pull of the VCO during key-up. The conditioning provides a stable 5.5V output by balancing the 5.5V reference with the 5.5V regulated supply. The output on U130B, pin 7 is applied to comparator U130D, pin 12, the non- inverting input. The output of U130D, pin 14 is applied to the base of current source Q135. The output of Q135 is on the emitter and is applied back to the inverting input of comparator U130D, pin 13. A decrease or increase at U130D, pin 13 causes a correction by U130D to stabilize the 9V transmit output. R140/141 establish the reference voltage on U130D, pin 13. C143 and C144 provide RF decoupling and C145 stabilizes the output. The 9V transmit voltage is then distributed to the circuits. 2.3POWER SUPPLIES REGULATED +9.6V The RF enable signal applied on J201, pin 5 and to the base of Q110 turning th…
