As forward biasing current increases, the impedance decreases to a low level. Therefore, the RF

level of the signal applied to Q6 increases as the bias current from the power control circuit

increases.

5.2.2.2 PA RF DEVICE (Q6)

Impedance matching for Q6 is provided by several capacitors, inductors, and sections of

microstrip. Q6 is an N-channel enhancement mode lateral MOSFET. The bias voltage (which is

required for the device to turn on) is controlled by the transmit signal. It is applied to the gate and

controlled by the logic through shift register U1. Therefore, this device is turned off in the receive

mode which improves isolation. Several capacitors, inductors, and resistors isolate this supply

from RF. Likewise, the 13-volt RAW BAT supply applied to the drain is isolated by similar

components.

From the output of the variable attenuator, the signal is fed to Q6. Q6 operates as a single-ended

device. It produces an output power of up to 35 watts.

5.2.2.3 FORWARD POWER DETECTOR, ANTENNA SWITCH,

LOW-PASS FILTER

The power control circuit senses Q6 output power to control the power output. A directional

coupler senses the forward power signal. This signal is then rectified by CR8 and applied to the

power control circuit. This signal is a DC voltage that increases in proportion to the level of

forward power. Refer to Section 5.2.2.4 for more information on power control.

PIN diodes CR9, CR11, CR12, and CR15 form an antenna switch that switches the antenna to the

transmitter in the transmit mode and the receiver in the receive mode. As stated in Section

5.2.2.1, PIN diodes have very high impedance when in the off mode and very low impedance

when forward biased. Transistors Q7 and Q9 are on in the transmit mode and off in the receive

mode.

In the transmit mode all four diodes are forward biased. The transmit signal then has a low

impedance path through CR9 to the low-pass filter and is blocked from the receiver by a

grounded quarter-wave line formed by C64, L15, and C66. A grounded quarter-wave lines

presents very high impedance at the non-grounded end. PIN diodes CR11 and CR15 and a second

quarter-wave line formed by C76, C77, and L17 provide additional isolation.

In the receive mode, all four diodes are in the off mode. Therefore, the receive signal from the

antenna is blocked from the power amplifier by CR9 and has a low impedance path through L15,

C74, L17, and C67 to the receiver in the RF module.

From the antenna switch the RF signal is applied to a low-pass filter formed by L11-L13 and

several capacitors and sections of microstrip. This filter attenuates harmonic frequencies above

the transmit band that could cause adjacent channel interference. R53 dissipates static buildup in

the antenna.

As forward biasing current increases, the impedance decreases to a low level. Therefore, the RF level of the signal applied to Q6 increases as the bias current from the power control circuit increases. 5.2.2.2 PA RF DEVICE (Q6) Impedance matching for Q6 is provided by several capacitors, inductors, and sections of microstrip. Q6 is an N-channel enhancement mode lateral MOSFET. The bias voltage (which is required for the device to turn on) is controlled by the transmit signal.
PAGE 2
The power control circuit maintains a constant power output as changes occur in power amplifier temperature and voltage. It does this by sensing forward power and then varying the drive to Q6 to maintain a constant output power. The drive to Q6 is controlled by varying the voltage applied to the variable attenuator circuit described in Section 5.2.2.1. In addition, the current applied to final amplifier Q6 is sensed, and if it becomes excessive, power is cut back to a low level.

lowers the power control voltage to the variable attenuator. This results in lowering the power output to approximately 25% of full power.

SECTION 6 ALIGNMENT PROCEDURE 6.1 GENERAL 6.1.1 INTRODUCTION The following alignment procedure should be performed if repairs are made that could affect the factory alignment or if adjustments may have changed for some other reason. To verify radio operation, the performance tests in Sections 6.5 and 6.6 can be run. To perform transceiver alignment, the following are required: • PC-compatible computer • Remote Programming Interface (RPI), Part No. 023-5300-000. • PCTune software, Part No. 023-9998-499.

• Windows® 95/98/NT/2000 (3.1 cannot be used) • Pentium® processor or equivalent • 16 MB of RAM • A hard disk drive with at least 3 MB of free space • A CD-ROM drive • An available serial port Software Installation Proceed as follows to install this software: 1. Close all applications that are currently running (other than Windows). 2. Insert the CD-ROM containing the PCTune software into the drive. 3. From the Windows taskbar, choose RUN and open SETUP.EXE on the drive being used.
