TPUPG2179TB 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 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
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

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tpupg2179tb.step`	99 KB	You want the bare part, or you mark your own boards.
`tpupg2179tb-etched.step`	2.0 MB	You want the part with `TPUPG2179TB` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 505 faces against 117 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
