Abstract: This work explores new ideas to improve the available microwave bandpass filters from different perspectives such as functionality, size reduction and performance. First five PCB-level filters are presented. The first filter is a dual-band tunable open loop resonator filter with individual frequency tuning. In the second section, a phase shifter is introduced as the main tuning component in tunable filters. The idea is presented in three different tunable filters. It is continued with a balanced wideband filter with high common-mode rejection. In addition, two wideband filters are presented in 0.13µm CMOS. A design procedure is provided which helps designers to design the same filters at other frequencies. The second CMOS filter is a balanced filter with high common-mode rejection. It is followed by introducing a new broadside coupled line structure. A PCB-level coupled filter and a Ka band chip filter in 0.13µm CMOS are presented to demonstrate the idea.
