摘要: This letter proposes a varactor-based filtering power divider that allows for reconfigurable operating frequency and bandwidth with high in-band isolation. A simple but effective tuning scheme was used to attain good impedance matching and isolation for all tunable states. Experimental results show that, for input return loss > 16.6 dB, the center frequency and 1 dB constant absolute bandwidth can be tuned from 1.3 to 2.08 GHz and from 70 to 130MHz, respectively. Moreover, this work demonstrates > 26 dB output isolation, < +/- 0.23 dB magnitude imbalance, and < +/- 1.3 degrees phase imbalance. Measured and simulated results are in good agreement.
