How to add power amp to output of a transciever

How to add power amp to output of a transciever to increase output power?

Adding the RF power amp to transmitter module seems be easy ,but transciever send and recieve signals in both directions ,how we can increase power of them by power amp modules?

If the transceiver has common input and output, to increase the output power you need to use two SP2 TX/RX switches. This could be FET, PIN, relay, etc. The switches are activated by the transceiver TX/RX command.

If it uses CIRCULATOR before anttena ,how we can add power amp?


Can we insert PA between RF_TX stage and circulator ? or we have to use circulator with higher power?

Why don't just put it at Tx path?

You can use the circulator after the PA, and not on the common RX/TX path near the antenna.
Usually small circulators could handle high power, but you have to check their spec.
