These devices are used as a “scratchpad” during program execution. 3.3.1 MICROCONTROLLER (U101) General Reset The control logic is based on an MC68HC11F1 eight-bit microcontroller (U101). This device has an internal 1K-byte static RAM and 512-byte EEPROM but no internal ROM or EEPROM.
CIRCUIT DESCRIPTION AUDIO/LOGIC DESCRIPTION (ALL MODELS) PE7 - This input senses the voltage on the IN3 pin of Option 1 slot wire-out W301. Address Bus The address bus consisting of A0-A15 is used for addressing the memory location in U107 or U108 that data is being written to or read from. In addition, it provides chip select signals to latches U110-U112. Refer to Section 3.3.2 for more information on memory and I/O addressing.
CIRCUIT DESCRIPTION AUDIO/LOGIC DESCRIPTION (ALL MODELS) and the data appears on data bus lines D0-D7. Chip select is performed by pulling the CE1 input (pin 20) low. The CE2 input is always pulled high by R114. The A13 and A14 address lines can be connected by changing jumpers if a 16K or 32K part is required. Data is read from U107 by pulling the OE input (pin 22) low. Likewise, data is written by pulling the WE input (pin 27) low. See the U104 description which follows for more information.

NAND gates U104A and U104D provide gating of the write signal to U108. Data is written to this device only during Flash programming. Therefore, when Flash programming occurs, the Q3 output (pin 16) of shift register U111 goes high which enables U104A. A double inversion of the write signal then occurs and it is applied to the WE input of U108.

CIRCUIT DESCRIPTION AUDIO/LOGIC DESCRIPTION (ALL MODELS) The passband of this filter is controlled by the Q1 output (pin 18) of latch U111. When LTR or digital Call Guard data or low-frequency Call Guard tones are received, this output goes high which turns Q300 on. This switches additional capacitance into the circuit and the filter cut-off frequency decreases to approximately 150 Hz. Then when high-frequency Call Guard tones are received, the output goes low and turns Q300 off.

The passband frequency of the filter is shifted in four steps using PIN diodes. These diodes are controlled by microcontroller through the Q2 and Q3 outputs of shift register U800.

CIRCUIT DESCRIPTION UHF TRANSMITTER DESCRIPTION 3.9 TRANSMITTER CIRCUIT DESCRIPTION (UHF MODELS) 3.9.1 FIRST AND SECOND AMPLIFIERS Impedance matching on the output is provided by L502, C570, C531, L506, and C532. Second amplifier Q507 is similar in design to Q506. These stages together produce about 20 dB of gain. The 8-volt supply to Q506 and Q507 is switched by Q504 similar to the revised 430-470 MHz version just described. Revised 430-470 MHz and all 470-512 MHz Models 3.9.
CIRCUIT DESCRIPTION UHF TRANSMITTER DESCRIPTION 3.9.4 ANTENNA SWITCH Impedance matching between Q508 and Q509 is provided by L501, several capacitors, and two sections of microstrip (microstrip is described in the preceding section). Resistor R523 lowers the Q of L501 to make it less frequency selective. Q508 is powered by the switched battery supply. AC signals are decoupled from this supply by C517-C519 and ferrite bead EP500.
CIRCUIT DESCRIPTION UHF TRANSMITTER DESCRIPTION 3.9.5 DIRECTIONAL COUPLER, LOW-PASS FILTER U500A, Q500/Q502 Operation The forward power signal from the directional coupler is applied to pin 2 of amplifier U500A. This is a DC signal that increases in proportion to forward power. The other input to U500A is a DC voltage from a D/A converter formed by shift register U801 and several resistors. This stage is similar in design to D/A converter U305 described in Section 3.4.4.
CIRCUIT DESCRIPTION 800/900 MHz SYNTHESIZER DESCRIPTION signal by 350. The TCXO frequency stability is 1.5 PPM, so this is also the stability of the synthesizer (and the second injection signal which is derived from the TCXO frequency). Over Current Shutdown Current to final amplifier Q601 on the PA board is monitored by sensing the voltage drop across R680. Pins 5 and 6 of U500B are effectively connected across this resistor.

CIRCUIT DESCRIPTION 800/900 MHz SYNTHESIZER DESCRIPTION 800 and 900 MHz). The logic levels on pins 3 and 4 of the VCO are as follows: VCO to the center of the operating band when the control voltage is at its midpoint. The output signal on the collector of Q902 is coupled by C911 to a buffer amplifier formed by Q901 and Q903. This is a shared-bias amplifier which provides amplification and also isolation between the VCO and stages which follow.
CIRCUIT DESCRIPTION 800/900 MHz SYNTHESIZER DESCRIPTION cially at the lower audio frequencies. Conversely, if only the reference oscillator was modulated, the VCO frequency would not change fast enough, especially at the higher audio frequencies. By modulating both, a relatively flat response is provided for all modulation frequencies. of C814. Therefore, base current does not change and the voltage on the emitter remains constant.
CIRCUIT DESCRIPTION 800/900 MHz SYNTHESIZER DESCRIPTION tional-N division with modulo 5 or 8 selection allows the loop frequency to be 5 or 8 times the channel spacing. With 800 and 900 MHz channels, modulo 8 is used to allow 6.25 kHz (12.5 kHz) channel spacing. This effectively AC grounds the receiver end of the quarter-wave line through CR802 and C847. When one end of a quarter-wave line is grounded, the other end presents a high impedance to the quarter-wave frequency.
CIRCUIT DESCRIPTION 800/900 MHz SYNTHESIZER DESCRIPTION 3.3.1. The input to the internal shift register of these devices is the DATA (U800/U801) or SDI (U802) pin, and the output of the last shift register stage in U800 and U801 is the QS pin. Therefore, serial data on the Data line from the audio/logic board (J201, pin 14) is first shifted into U801, then U800, and then U802. divide number. In this example the fractional-N increment is .75 x 8 (modulo N) or 6.
CIRCUIT DESCRIPTION 800/900 MHz RECEIVER DESCRIPTION For example, if current through R207 attempts to increase, the emitter voltage of Q200 decreases. Q200 then conducts less and turns Q201 off slightly to maintain a constant bias current. This provides a stable bias over changes in temperature. from intermodulation, and other undesired frequencies. Impedance matching between this filter and U201 is provided by C271, C272, L215, and R228.
CIRCUIT DESCRIPTION 800/900 MHz TRANSMITTER DESCRIPTION 3.12 TRANSMITTER CIRCUIT DESCRIPTION (800/900 MHz MODELS) If a narrowband channel is selected, a low signal is applied to the base of Q205. That transistor is then turned off and inverter Q206 turned on. CR209/CR210 are then forward biased and CR207/CR208 reverse biased. This routes the 450 kHz IF signal through Z202 and blocks it from Z206. If a wideband channel is selected, the opposite occurs.
CIRCUIT DESCRIPTION 800/900 MHz RECEIVER DESCRIPTION Switching transistor Q602 is controlled by the transmit signal from the Q7 output (pin 11) of shift register U801. This is the same signal that controls transmit 8-volt supply switch Q505/Q504. This signal is high in the transmit mode and low in the receive mode. Therefore, Q602 turns on in the transmit mode and current flows from the collector of Q601 through R610, R609, CR604, L604, CR602/R602, and L602.
CIRCUIT DESCRIPTION 800/900 MHz TRANSMITTER DESCRIPTION fier temperature or transceiver voltage is excessive as just described in Section 3.12.4. oped across R606 and then fed to the power control circuit. Reverse power is not detected in this transceiver. U500A, Q500/Q502 Operation From the directional coupler the transmit signal is fed to a low-pass harmonic filter formed by C624C627 and several sections of microstrip. This filter attenuates harmonic frequencies occurring above the transmit band.
CIRCUIT DESCRIPTION 800/900 MHz TRANSMITTER DESCRIPTION Over Current Shutdown Current to the second and third amplifier stages in power module U600 on the PA board is monitored by sensing the voltage drop across R601. Pins 5 and 6 of U500B are effectively connected across this resistor. As current increases, the voltage on U500B, pin 6 decreases which causes the output voltage on pin 7 to increase. The gain of each U500B input is set at about ten by R509/R504 and R502/R507.

COMPONENT LOCATOR GUIDES RF BOARD COMPONENT LOCATOR GUIDE (UHF) The following guide can be used to locate components on the 430-470 and 470-512 MHz RF board layouts on pages 6-8 and 6-11. Refer to the grid around the board to determine the approximate location of a component. NOTE: When the location of a component is different on the board unrevised 430-470 MHz board, the location on the unrevised board is listed first and the location on the revised 430-512 MHz board is listed second.
