Abstract

In this paper, we propose a scheme to design the
reconfigurable filtering power divider with arbitrary operating
channels based on external quality factor (Qe) control. By using
an input feeding line, n resonators, and m output feeding lines,
the nth-order m-way filtering power divider topology can be
obtained with a simple configuration. A coupled-line output
feeding structure loading with multiple PIN diodes is proposed
to adjust the output Qe values. Design theories for obtaining
the desired Qe values are provided. Then, the filtering power
divider can be fully reconfigured in the states with one to
m operating channels. Good input matching can be achieved
without using an additional reconfigurable impedance matching
network in all these states, resulting in a size and loss reduction.
For verification, a 2nd-order 4-way reconfigurable filtering power
divider is designed, fabricated, and measured. As compared to
the reported reconfigurable power dividers, the proposed design
shows the merits of fully reconfigurable operating channels,
favorable filtering responses, low insertion losses, high isolation,
and a simple structure.
