Abstract EN
This paper presents a novel method to design dual-band bandpass filters with tunable lower passband and fixed upper passband.
It utilizes a trimode resonator with three controllable resonant modes.
Discriminating coupling is used to suppress the unwanted mode to avoid the interference.
Varactors are utilized to realize tunable responses.
The bandwidth of the two bands can be controlled individually.
Transmission zeros are generated near the passband edges, resulting in high selectivity.
For demonstration, a tunable bandpass filter is implemented.
Good agreement between the prediction and measurement validates the proposed method.
