band stop filter+gsm
Hi guys , i want to design a bandstop filter in gsm frequency ( 870 Mhz - 960 Mhz ) with hfss , I am an amateur. This filter is for transmittering antenna and my prof wants the filter's capacity upto 200 watt , I have searched about high power filters but I can't find anything useful... The other problem is that I want to design a microstrip filter but the microstrip filters can't work in this power, can they? in the first stage I want to find the best circuit for my purpose ( using this filter for transmitter antenna ) and then convert it into microstrip form , and if I couldn't design this filter in 200 watt I want to know if I can use an amplifier after the output of the filter?If anyone have an example or any good article or book please help me with this , this is my first project and it is very hard for me . thanks
