rf transmitter / reciever

rf transmitter / reciever

rf transmitter / reciever

(OP)
How do you keep transmitter leakage power from frying the reciever in a single antenna wireless application.


In that same circuit how would you determine the duplexer isolatoin  to prevent the transmiter from interfering with low level reciever signals.  T = 300K   BW = 300kHz    

Reciever noise figure is 2dB  Transmitter output power = 1W

RE: rf transmitter / reciever

use pin diodes to shunt the signal and a quarter wave transformer between the antenna and pin diode at the frequency of transmission - assuming it is the same as the reception freq
or do you want to use the system in duplex mode?
try a search on amwireless for t/r switches
