Multi-Band Bandpass and Bandstop RF Filtering Couplers With Dynamically-Controlled Bands
This paper reports on multi-band bandpass and bandstop RF filtering four-port couplers with programmable bands in terms of center frequency and number of passbands/stopbands. They are based on four multi-resonant bandpass/bandstop-type modules that are inter-coupled by means of 90°/270&am...
