Hello, I am building a microwave Xband transceiver and I would like to know if it is a good practice to include an isolator:
1. before every attenuator
2. before every filter
3. before the antenna to the transmit side, before a bidirectional coupler, that is connected directly to the antenna.
4. after the local oscillator and before the oscillaror low pass filter.
Do I also need to include an isolator after a bandpass filter? (do the reflected power from the next stage from the filter, affect the filter parameters?)
5. Any other place to include isolators?
