Abstract

An apparatus may include a filtering network and a switch. From an amplified signal, the filtering network produces a filtered signal for wireless transmission in a frequency band. The switch includes a first terminal, a second terminal, and a switching element. The first terminal receives the filtered signal and the switching element selectively couples the first and second terminals. The filtering network also attenuates harmonics of the filtered signal that are generated by the switch. This attenuation establishes compliance with a harmonic emissions power limit associated with the frequency band. More particularly, this attenuation reduces at least one of the harmonics from a level exceeding the harmonic emissions power limit to a level within the harmonic emissions power limit.
