Today, i was working on my 2,6 GHz Power Amplifier.
I replace the input circulator with a little piece of coax and replace the output circulator with a piece of PCB to elevate another piece of coax with greater diameter for high output power, the PCB is for ground purposes too.
I try my best to modify this bad boy, first time for me.
If you have some idea, keep me in touch ! 👍🤘🔊📺📡📻😎

The input connector was removed and replaced with SMA connector, perfect for the amplifier cover.
RF Isolator and output connector removed and soon replaced by a small piece of coax and another connector. 👍
Which connector can i use on the PCB directly ? 🧐🤔
