TRF37B75IDSGR 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; the recommended supply is 4.5 V to 5.25 V (5 V nominal), and the absolute maximum supply input is 6 V. |
| 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; connect the pad to GND for board-level reliability. |
| 4 | NC | unconnected | No electrical connection; connect the pad to GND for board-level reliability. |
| 5 | PWDN | input | Power-down control: when high the device is in power-down state, and when low or not connected it is active; it has an internal pulldown to GND, with VIH of 2 V minimum and VIL of 0.8 V maximum. |
| 6 | NC | unconnected | No electrical connection; connect the pad to GND for board-level reliability. |
| 7 | RFOUT | output | RF output and DC bias (VCC): connect to the DC supply through an RF choke inductor and to the output load through a DC-blocking capacitor; internally matched to 50 Ω. |
| 8 | NC | unconnected | No electrical connection; connect the pad to GND for board-level reliability. |
| 9 | GND | power_in | PowerPAD RF and DC ground; connect to the PCB ground plane, and the pad must be soldered to the board for thermal and mechanical performance. |
