cwjcwjcwj,
I have to design a diplexer for using a single antenna in a Tx/Rx scheme. The only restriction is that stripline technology must be used. Have you got any idea?. The freq are Tx=2.223 GHz and Rx=2.047 GHz. What kind of filters should I use (interdigital, combline, coupled resonators,...)?
thank you very much in advance
