摘要： According to one exemplary embodiment, a switching module includes a first harmonic phase tuning filter coupled to a first input of an RF switch. The first harmonic phase tuning filter is configured to provide an output impedance that substantially matches an input impedance of the RF switch at approximately a fundamental frequency and to provide a low impedance at approximately a harmonic frequency generated by the RF switch. The first harmonic phase tuning filter includes an LC circuit coupled between an output terminal of the first harmonic phase tuning filter and a ground and tuned to provide the low impedance at approximately the harmonic frequency generated by the RF switch. The RF switching module further includes a second harmonic phase tuning filter coupled to a second input of the RF switch. The first and second harmonic phase tuning filters can be fabricated on a single semiconductor die.
