Hi all,
I have a 15kW transmitter on a antenna. The duty cycle of the transmitted signal is about 20%. In between two Tx-events, I want to use another low-power source to measure impedance changes on the antenna by measuring the reflected power. The frequency is 100MHz on the high-power Tx, and 200MHz on the low-power (the antenna is tuned for both frequencies); the whole setup works with 50ohms
I am looking for a high-power fast switching (PIN diode) network, which connects the two different transmitters and secures the low-power setup from the high-power part (circulators?)
Since I am more a "RF utilizer" rather than "RF engineer", any suggestion is welcome. Off-the-shelf solutions preferred, but I do have a solder station ready as well.
Thanks a lot in advance.
