Balanced Quad-Band Bandpass Filter With Controllable Frequencies and Bandwidths
A balanced microstrip quad-band bandpass filter (BPF) employing balanced microstrip/slotline (MS) transition structures and two pairs of folded asymmetric short stub-loaded resonators (ASSLRs) is presented in this paper. The center frequencies of the four differential-mode (DM) passbands can be cont...
