TRF37C73IDSGR

Texas Instruments · RF Amplifiers · WSON-8-EP(2x2)

TRF37C73IDSGR from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VCC power_in DC power supply input; nominally 3.3V with operating range 3V to 3.45V.
2 RFIN input RF input internally matched to 50Ω; connect to source through DC-blocking capacitor.
3 NC unconnected No electrical connection; connect pad to GND for board level reliability.
4 NC unconnected No electrical connection; connect pad to GND for board level reliability.
5 PWDN input Power down control with internal pulldown resistor to GND; high logic level disables device.
6 NC unconnected No electrical connection; connect pad to GND for board level reliability.
7 RFOUT output RF output internally matched to 50Ω; connect to load through DC-blocking capacitor and to VCC through RF choke inductor.
8 NC unconnected No electrical connection; connect pad to GND for board level reliability.
9 GND power_in PowerPAD thermal pad for RF and DC ground; must be soldered to PCB ground plane for thermal and mechanical performance.
