Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | RF2 | passive | RF port 2 of the SPDT switch. Connects to the RFC common port when VC2=High and VC1=Low. Requires a series DC-blocking capacitor (C1=56 pF typical for operation >500 MHz). 50 Ω system impedance. |+| 2 | GND | power_in | Ground reference for the switch. Must be tied to system ground with a low-inductance connection for proper RF isolation and grounding at DC-3 GHz. |+| 3 | RF1 | passive | RF port 1 of the SPDT switch. Connects to the RFC common port when VC1=High and VC2=Low. Requires a series DC-blocking capacitor (C1=56 pF typical for operation >500 MHz). 50 Ω system impedance. |+| 4 | VC1 | input | Digital control input 1. Selects the RFC-to-RF1 path when High (2.8V to 5V) with VC2 Low. Low level -0.2V to 0.2V. Absolute max -6.0V to +6.0V with |VC1-VC2| ≤ 6.0V. Control current typ. 4 µA (max 100 µA). |+| 5 | RFC | passive | Common RF port of the SPDT switch, routed to either RF1 or RF2 depending on the state of VC1/VC2. Requires a series DC-blocking capacitor (C1=56 pF typical for operation >500 MHz). 50 Ω system impedance. Max RF input power 33 dBm (>500 MHz). |+| 6 | VC2 | input | Digital control input 2. Selects the RFC-to-RF2 path when High (2.8V to 5V) with VC1 Low. Low level -0.2V to 0.2V. Absolute max -6.0V to +6.0V with |VC1-VC2| ≤ 6.0V.
