The RF Workbench / 100W Linear PA for the FM Band
« on: October 09, 2020, 0737 UTC »
Hi folks. This is my very first post to this forum. I am a radio HAM based in the mountains in North India.
I am working on a project that involves using a SDR Radio to output multiple FM signals, and researching the power stage part of the design.
I need about 1W average per signal, and there may be upto 10 carriers, so 10W average Power. So this probably means an amplifier capable of upto 100W of output power. It also needs to be a linear amplifier.
I was wondering if anyone had pointers where I can start looking for designs I can build or purchase. I came across these reference designs based on the MRF101AN and wonder if they can do the job

Thoughts?
