I have finished a Cavity filter ,Bandpass:869-894
and 896-2G>20dB.
When I test power capability ,
The PEP power =55dBm is ok
The AVG power=51dBM have some problems
when i tested at 894MHZ I found the POWER METER showed the VSWR is being larger and the passing power being smaller.

I have made a Duplexer simulation in designer .I simulated Rx filter and Tx filter seperately frist.Then I combine them with Ant port ,I find the return loss is bad .I do not know how to tun it to better ,anybody can help me ?the attachment is my simulation picture.3ku.
this hole does not ininfluence function of cavity filter!I feel it is good for me to test filter in humid air.dou you have any good idea for Static Humidity testing.
And the hole 's position 's problem ....which position is the best on the cavity ????
