摘要

提出了一种中心频率和带宽连续可控的双可调谐发夹滤波器。通过在高频段引入一个可调谐的传输零，增加了阻带衰减和频带隔离。中心频率可调是通过加载滤波器谐振器来实现的，而带宽是由相邻谐振器之间的变容控制的，它控制了谐振器间的耦合。该滤波器的中心频率范围为900MHz ~ 1.1GHz，带宽范围为40MHz ~ 80GHz。可调谐的传输零频率范围在1GHz至1.3GHz之间，以实现上频段30dB以上的阻带衰减。实验验证了该滤波器的性能。

Reconfigurable Hairpin Filter with Tunable Center Frequency, Bandwidth and Transmission Zero

This paper presents a twofold tunable hairpin filter with continuously controllable center frequency and bandwidth. Stopband attenuation and band isolation is increased by introducing one tunable transmission zero for the upper frequency bands. Center frequency tunability is achieved by loading the filter resonators, while the bandwidth is controlled by varactors between adjacent resonators, which control the inter-resonator couplings. The presented filter is designed for a center frequency range from 900MHz to 1.1GHz and for a bandwidth between 40MHz to 80GHz. The tunable transmission zero frequency range is between 1GHz to 1.3GHz to achieve a stopband attenuation above 30dB for the upper bands. The filter performance is experimentally validated.
