RFDIP2009L51AT from Walsin Tech Corp, in a 0805. 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 | GND | passive | Ground return terminal. Connect directly to the PCB RF ground plane with a low-inductance path for proper 50 Ω impedance reference. |
| 2 | COMMON | passive | Common (antenna) port. 50 Ω single-ended RF port carrying the combined low-band (699 ~ 960 MHz) and high-band (1427 ~ 2690 MHz) signals. Route as a 50 Ω controlled-impedance trace. |
| 3 | GND | passive | Ground return terminal. Connect directly to the PCB RF ground plane with a low-inductance path for proper 50 Ω impedance reference. |
| 4 | HIGH_BAND | passive | Higher-frequency port for the 1427 ~ 2690 MHz band. 50 Ω single-ended RF port; typical insertion loss 0.6 dB, max 0.75 dB at +25 °C. Route as a 50 Ω controlled-impedance trace. |
| 5 | GND | passive | Ground return terminal. Connect directly to the PCB RF ground plane with a low-inductance path for proper 50 Ω impedance reference. |
| 6 | LOW_BAND | passive | Lower-frequency port for the 699 ~ 960 MHz band. 50 Ω single-ended RF port; typical insertion loss 0.62 dB, max 0.7 dB at +25 °C. Route as a 50 Ω controlled-impedance trace. |
