- Pin Count: It has 8 pins.
- Pin Functions:
- RF1 (Pin 1): RF port 1, one of the switchable paths.
- GND (Pin 2): Ground connection.
- CTL (Pin 3): Control pin for toggling the switch between RF paths.
- NC (Pin 4): No connection; often used for mechanical stability.
- RF2 (Pin 5): RF port 2, the other switchable path.
- GND (Pin 6): Ground connection (internally connected to the paddle).
- Vdd (Pin 7): Supply voltage.
- RF COM (Pin 8): Common RF port for input/output.
The switch operates by using control voltage applied to the CTL pin to route the RF signal between the RF1 and RF2 ports, with RF COM serving as the shared input/output path.
