Hello all, I am planning on using a USRP B200 in a half-duplex communication system to communicate with a CubeSat. The TX/RX port will be used for transmitting and the RX2 port for receiving. The transmitting port will be connected to a power amplifier with a 60W output, this will in turn connect to an RF switch which will switch between the TX/RX (transmitting) and RX2 (receiving). The RF switch has an isolation of ~40-43 dB which means from the 47.78 dBm transmitted we will have roughly 5-8 dBm reflected to RX2. Since the SDR is only rated to receive maximum 0 dBm I'm wondering if someone has any ideas on how to handle this. I'm unsure if this power will simply fry the board and I should implement a power limiter or if there are other workarounds.
Appreciate any help you can provide. Best regards, Martin Elfvelin
