Abstract
According to one embodiment, a radio frequency (RF) frontend circuit includes a RF receiver, a transceiver (or transmit/receive) switch, and a high-order inductive degeneration matching network coupled in between the transceiver switch and an input port of the RF receiver, where the high-order inductive degeneration matching network matches an impedance for the RF receiver and the transceiver switch and the high-order inductive degeneration matching network is to resonate at a plurality of predetermined resonant frequencies.
