Abstract

A communication matching network for multi-harmonic suppression includes a communication circuit configured to provide a signal. The communication matching network further includes a matching circuit configured to receive the signal from the communication circuit and suppress one or more harmonics of the received signal to generate a filtered signal, wherein the matching circuit includes a transformer comprising a first winding and a second winding, wherein the first winding includes a first inductance and the second winding includes a second inductance and wherein the matching network includes a harmonic trap including a third inductance such that the third inductance is located inside or within a physical layout of the first winding and/or the second winding. The communication matching network further includes a receiver circuit configured to receive the filtered signal from the matching circuit for further processing.
