Preliminary Project Information


RF Power Amplifier Controller is a PIC18F4550 project and is designed for radio amateurs looking for some boost to their 10W radios.

Project is designed for combining 4 RF Power Blocks with Input Splitter and Output Combiner to obtain high power from economical transistor blocks consisting IRF510 Type FETs.

Interesting features of this project:

1. LCD 4x20

2. 3 Button Menu Operation

3. Generates Band Relay info.

4. RF Activated. Generates PTT for RF Modules

5. Supports 4 of i2C type remote Sensors

6. RF Power Output and SWR Measurement to 1KW

7. RF Input Measurement (Max. 10W)

8. Over Voltage, Current, Temp, SWR Warnings

9. Designed for 4 RF Amplifier Modules with input splitter and output combiner

10. PIC Firmware by Tony/I2TZK
