TECH PUBLIC · RF Switches · SOT-363

TPHWS314 from TECH PUBLIC, in a SOT-363. 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. Connected to the switch's RF common (RFC) when VC1=0, VC2=1. Requires an external DC blocking capacitor (CB=51 pF for operation above 500 MHz). 50 Ω system impedance.
2 GND power_in Device ground. Connect to system RF/DC ground with a low-inductance path.
3 RF1 passive RF port 1. Connected to the switch's RF common (RFC) when VC1=1, VC2=0. Requires an external DC blocking capacitor (CB=51 pF for operation above 500 MHz). 50 Ω system impedance.
4 VC1 input DC control voltage 1. Logic '1' = +2.7 V to +5 V, logic '0' = 0 V to +0.2 V. Absolute maximum control voltage +6 V. Typical control current ~5 µA (100 µA max). Selects the RFC-to-RF1 path when high.
5 RFC passive RF common port. Routed to RF1 or RF2 depending on VC1/VC2 logic state. Requires an external DC blocking capacitor (CA=51 pF for operation above 500 MHz). 50 Ω system impedance; max RF input power +34 dBm (0.5-2.5 GHz).
6 VC2 input DC control voltage 2. Logic '1' = +2.7 V to +5 V, logic '0' = 0 V to +0.2 V. Absolute maximum control voltage +6 V. Typical control current ~5 µA (100 µA max). Selects the RFC-to-RF2 path when high.
