3-3. Forward/Refl ect power detector circuit

The forward / Refl ect power detector circuit consists of 

a CM coupling type detection circuit formed by a Micro strip 
line and the differential amplifi er IC4.

A part of the transmitter power is detected by diodes D9 

and D10 and is converted into DC voltage.

3-4. Harmonic fi lter circuit

The harmonic filter circuit uses a three-stage “pi” type 

Chebyshev type LPF.

This circuit removes harmonics from the transmitter out-

put and sends the fi ltered signal to the antenna connecter 
(CN22).

3-5. APC circuit

The APC circuit stabilizes the transmitter power so that 

the output power specifi ed by the Control Voltage from the 
MPU is obtained.  It consists of a Forward/Refl ect power de-
tector circuit and Differential amplifi ers (IC2 and IC5).

It compares the voltage detected by the Forward/Refl ect 

power detector circuit (voltage detected by the Forward 
Power) and the Control Voltage (PWR_CONT) from the 
MPU (IC802: X56-311 A/3).  It stabilizes the output power by 
changing pin 2 (Vgg).

The voltage detected (that detected Reflect Power) by 

the Forward/Reflect power detector circuit is compared to 
the Control Voltage (PWR_PRT) from the MPU (IC802: 
X56-311 A/3).  When a load V.S.W.R.  is connected to the 
Antenna Connecter and is more than 1.5, it functions so that 
the output power gets smaller as the detection voltage (that 
detected Refl ect Power) gets larger.

3-6. High temperature detector circuit

The high temperature detector circuit consists of a ther-

mal switch IC (IC7) and a switching FET (Q2).

This circuit lowers the transmitter power when the fi nal 

unit temperature is too high (90°C or higher).
