1. A system, comprising:
a radio frequency port coupled to an external connector;
a microstrip line coupled to the radio frequency port and one or more components mounted on a printed circuit board; and
a short coupled to the microstrip line and a ground reference, wherein the short is coupled to the microstrip line proximate the radio frequency port, wherein the short is configured to have a higher characteristic impedance than the microstrip line, wherein the short is configured to suppress one or more harmonics of an operating frequency for radio frequency signals transmitted or received via the radio frequency port.
