摘要: A compact switchable microstrip tri-band bandpass filter with a wide stopband is presented in this paper. Thanks to the low loading effect of distributed coupling technique, three channels can be obtained without conventional complicated matching network. Three passbands turned on and off independently by using p-i-n diodes. To validate design concept, theory as well experiment compared
