Hai
All

The 2 ways amplifier with 500mW to 1 watt(23 dBM) output power seems very rare.
Could someone here spotted the links?

Thank you
Jeckson
 

Do you mean bidirectional amplifier?
FYI
500mW = 27dBm
1watt = 30dBm

Yes



500mW = 27dBm

or

1watt = 30dBm

for PO(power output)

and maybe with LNA for received.

Maybe links...

Thank you very much
Jeckson
 

What do you have in mind? If you are thinking 2-way communications, a power amplifier on the transmit side and LNA on the received side, combine the two amplifiers using a coax directional coupler. One of many trade-offs is to have sufficient isolation between the two so as not to distort / destroy the LNA.

Sorry ..I meant like this...If no LNA at receiver..nevermind.



Thank you

nevermind without LNA

Thank's

This configuration is realizable of course but don't forget to arrange the impedance matching circuits for LNA and PA.
Because matching circuits will be completely different and you should care also TX/RX switching.
PA and LNA can not work simultaneously.
 


Thank's

Sure...

I'm looking schematics or maybe modules for that frecuencies.

Thank you
