TRF37C75IDSGR 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 bias supply pin for the amplifier; the datasheet recommends a 4.5 V to 5.25 V supply (5 V nominal). |
| 2 | RFIN | input | RF input, to be connected to the RF source through a DC-blocking capacitor; internally matched to 50 Ω. |
| 3 | NC | unconnected | No electrical connection; the datasheet says to connect the pad to GND for board-level reliability. |
| 4 | NC | unconnected | No electrical connection; the datasheet says to connect the pad to GND for board-level reliability. |
| 5 | PWDN | input | Power-down control: high puts the device in power-down state, while low or NC leaves it active; an internal pulldown resistor to GND is present. |
| 6 | NC | unconnected | No electrical connection; the datasheet says to connect the pad to GND for board-level reliability. |
| 7 | RFOUT | output | RF output and DC bias (VCC): feed VCC through an RF choke inductor and take the RF output through a DC-blocking capacitor; internally matched to 50 Ω. |
| 8 | NC | unconnected | No electrical connection; the datasheet says to connect the pad to GND for board-level reliability. |
| 9 | GND | power_in | Exposed PowerPAD serving as the RF and DC ground; it must be soldered to the PCB ground plane for thermal and electrical performance. |
