Juan,
You are probably going to have to build an amplifier, but many RF modules only require 40mw drive. I am building 80w 2m amplifiers using the Toshiba S-VA36: http://www.kl7uw.com/kits.htm
Other modules in that line such as S-VA10H outputs up to 14w. They all require pretty much the same pc board. I am using the board made by W6PQL which costs $17.50 without parts. Parts for the 80w amp are listed on Mouser as a special project which is linked from: http://www.w6pql.com/2_meter_80w_all_mode_amplifier.htm
If you did not want 80w output one could substitute the 10, 25, or 50w RF modules: https://www.rfparts.com/module/rfpower-mosfet.html
Not sure what you mean by "pass through" unless you mean an amp that bypasses for Receive. The W6PQL does that and has ckt for RF sensed keying in transmit or external PTT. I've enhanced the design with addition of power output metering and temp-controlled cooling fan.
But building in limited quantities means the parts are not cheap.

I'm looking for some information about using some ettus SDR for sat work. I have a B210. What kind of amplifier can I use able to be driven with the 200 mW of the Tx/RX output, better if it's pass trought. My google search was unable to find some ham who has made somethin similar Is ther some similar work with another SDR? I would appreciate any kind of help... I'm a newbie... Thanks a lot. 73 Juan EB2FVT
