摘要：

A new class of adaptive Wilkinson-type filtering power divider that simultaneously exhibits single/multi-band operation, frequency tuning, and controllable number of passbands is reported. It exploits the incorporation of single/multi-band quasi-bandpass sections into the input/output terminals of the power divider, whose quarter-wavelength-long transmission-line segments are reused as impedance inverters between the quasi-bandpass stages. In this manner, bandpass-type transfer functions are realized at the output nodes along with the power-distribution functionality. For experimental validation, a reconfigurable dual-band prototype that features tunable passbands in the range 0.8-1.2 GHz is designed, manufactured, and tested.
