High-order balanced bandpass filters that are continuously tunable in terms of frequency and bandwidth (BW) and can be intrinsically switched-off. The filters include multiple resonant sections cascaded between a differential RF input and a differential RF output. The resonant sections comprise at least one multi-resonant cell and at least one transmission pole cell. The multi-resonant cell includes four frequency tunable resonators, and is configured to create a frequency tunable pole at the center frequency of the filter, and two frequency tunable transmission zeroes at resonating frequencies of the resonators of the multi-resonant cell. The transmission pole cells each include two resistively-terminated frequency-tunable resonators configured to resonate at the center frequency of the filter.
A balanced/differential bandpass filter comprising:
