in my dual band filter (f1=1.8GHZ and f2=5.4 GHZ) can i use quarterwave transformer instead of dual frequency transformer for impedance matching? is there any other possible way to match the impedances..?
it is dualband bandpass filter.. band 1 has center freq.1.8GHZ and band 2 has 5.2GHZ.. i am designing it using SIRs.. input impedance is 50ohm but i hav choosen SIR impedance as 86ohm.. can i match these two impedances by using quarterwave transformer or some other else? or no need as you said?
