| 摘要 |
The invention relates to a high frequency switch used in a communication apparatus or the like, such as a portable terminal. The switch includes a first signal terminal, a first diode, the cathode of which is directly or indirectly connected to the first signal terminal, a bias controlling device having an end which is connected to the anode of the first diode, a second signal terminal directly or indirectly connected to the anode of the first diode, an impedance converting device having an end which is directly or indirectly connected to the first signal terminal, a serial circuit having a high frequency voltage dividing device and a second diode, the serial circuit being connected to the other end of the impedance converting device, and a third signal terminal directly or indirectly connected to the other end of the impedance converting device.
