LFB321G40CM8D710 from Murata Electronics, in a 1210. 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 | IN | passive | RF input port. 75 ohm nominal port impedance. Accepts RF signal in the 1125-1675 MHz pass band (fo = 1400 MHz ± 275 MHz). Marked with directional input mark 'A' on the package top. |
| 2 | GND | passive | Ground reference terminal. Provides the RF ground return for the band pass filter network; should be connected to a low-impedance PCB ground with a via array beneath the pad. |
| 3 | OUT | passive | RF output port. 75 ohm nominal port impedance. Delivers the band-pass filtered RF output centered at 1400 MHz with insertion loss ≤ 1.80 dB at 25 °C. |
