Re: 6 channel multiplexer
I think it is a very difficult thing.if the loss is't the question ,then ,you can sue circulator
Added after 44 minutes:
sorry,IT is useful only for duplexer.
HOW the high pass filter used for ? the power handling needed?
the high mode can be estemited and by properly design,can be out of the passband i think.
first ,I think your question is not how to design the RF front end,but the base knowlege of the system.you should have more base kowlege of this subject.you can find some book in the UESTC .
Re: gain compression
the gain is not the same as the signal becoming larger because of the non-learner,
when the sinal is large to some level the gain is becoming small and the compression come\\
Re: A RF studen's question
i think the most important thing is learn at your free time
something sames not about your curent work may be usefully for your later work and there is not anywork is for a lifetime if you don't learn
the center frequency is 830MH,and the 2dB bandwidth is 10MH,and in the 2.5MH offside hte loss is larger than 23dB??
and in room temperature the return loss is larger than -20
I designed a coaxial filter in comuniciation frequency
in the room temperature it is good ,but when the temperature is -25℃，to my strange ,part of my products is good ,but the other part is bad .
and when the tempertaure is back to room temperature,the vswr can't back to good,who can tell me...
