ABSTRACT:
A high-frequency switching module in which a high-frequency switch including a diode, which functions as a switching device, and a high-frequency filter including inductors and a capacitor are integrated with each other. The inductor defining a π-type high-frequency filter is connected directly and in series to the diode. By inserting the inductor, the cut-off frequency of a Chebyshev-type low-pass filter circuit produced when the diode is turned ON can be shifted to a lower frequency side, and also, the ripple can be suppressed to a small level.
