Abstract
Official abstract text for this publication.
A frequency-selective circuit includes a signal input port, a signal output port, and a frequency response control block. The frequency response control block includes a mixer module and a filter module. The mixer module has a first port electrically connected to a signal path between the signal input port and the signal output port, a second port electrically connected to the filter module, and a local oscillator (LO) port. The mixer module operates according to an LO input received by the LO port. The filter module is electrically connected to the second port of the mixer module.
