Circuit diagram 500mW FM PLL transmitter 88-108MHz using LMX3206 – PIC16F870
500mW PLL FM transmitter 88-108MHz
This PLL transmitter is controlled and the frequency is very stable and can be programmed digitally.
Transmitter will work 88-108 MHz and output power up to 500mW.
With a small change can set the frequency of 50-150 MHz.
The output power is often set to several watts with transistors.
So therefore I decided to [...]
