There's a huge number of SOI and III-V RF switches out there with a wide range of linearity
@power, isolation and nuances (like, if this is a radar, switching speed is a limit to min distance (time of flight vs time to flip)). Many stacked-FET switches have slow gate networks.
You also need to know when you are TXing and RXing to protect the RX front end, OK if it's radar but not so much for random time of arrival comms.
The circulator is the approach for true bidirectional full duplex, switches front ends are for time-division multiplexing architecture.
