HIGH FREQUENCY SWITCHING MODULE AND METHOD FOR ADJUSTING FREQUENCY CHARACTERISTIC OF HIGH FREQUENCY CIRCUIT |
摘要 |
To obtain a high-frequency switching module and a frequency-characteristic adjusting method for a high-frequency circuit in which a desired frequency characteristic can be exhibited and the ripple can be suppressed to a small level. A high-frequency switching module in which a high-frequency switch SW including a diode D, which serves as a switching device, and a high-frequency filter LPF including inductors L and L1 and a capacitor C1a are integrated into each other. The inductor L forming a À-type high-frequency filter is connected directly and in series to the diode D. By inserting the inductor L, the cut-off frequency of a Chebyshev-type low-pass filter circuit formed when the diode D is turned ON can be shifted to a lower frequency side, and also, the ripple can be suppressed to a small level. |
