A tunable bandpass filter with switchable single‐/dual‐band responses is presented. The single‐band to dual‐band transformation is achieved by controlling frequencies of poles in a passband. The frequencies of poles are adjusting by using a coupled structure with two coupling capacitors. A filter with both 4‐pole single‐band and 2‐pole dual‐band characteristics is built on a Duroid substrate with εr = 3.0 and h = 30 mils. The tuning of the center frequency and the passband transformation are done using silicon varactor diodes. In the 4‐pole single‐passband mode, a center frequency tuning of 1.0 to 1.4 GHz is achieved with 1‐dB bandwidths of 150 to 198 MHz. The 2‐pole dual‐band bandpass filter mode has the center frequency tuning of 1.0 to 1.29 GHz (low‐band) and 1.4 to 1.58 GHz (high‐band). The application areas are in wideband cognitive radios.

1.0至1.58 GHz可调带通滤波器,具有可切换的单/双频带响应

提出了具有可切换单/双频带响应的可调带通滤波器。单频带到双频带的转换是通过控制通带中极点的频率来实现的。通过使用带有两个耦合电容器的耦合结构来调整极点频率。与4极单频带和2极二者双频带特性的滤波器是建立一个的Duroid基板上ε - [R = 3.0和ħ= 30密耳。使用硅变容二极管来完成中心频率的调谐和通带变换。在四极单通带模式下,使用150至198 MHz的1 dB带宽可实现1.0至1.4 GHz的中心频率调谐。2极双频带通滤波器模式的中心频率调整为1.0到1.29 GHz(低频带)和1.4到1.58 GHz(高频带)。应用领域是宽带认知无线电。
