High-frequency switch module |
摘要 |
A high-frequency switch module includes a switch IC. An impedance matching circuit is connected to the antenna port of the switch IC. The impedance matching circuit includes a high-pass filter and a low-pass filter. The high-pass filter is disposed on the side of the antenna port, and is a substantially L-shaped circuit including a capacitor and an inductor. The antenna port is connected to the ground by the inductor.
