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 | LB | passive | Lower Frequency Port (Low Band, e.g. 1570-1610 MHz band on 2R450G diplexer). 50 Ω single-ended RF port; presents high impedance out-of-band so it does not load the Common Port at high band frequencies. |+| 2 | GND | passive | Ground pad. Tied together with pins 4 and 6 to the RF ground plane for proper shielding and return current. |+| 3 | COM | passive | Common Port. 50 Ω antenna/common node where the low-band and high-band signal paths are combined; typically routed to the antenna or shared radio pin. |+| 4 | GND | passive | Ground pad. Tied together with pins 2 and 6 to the RF ground plane. |+| 5 | HB | passive | Higher Frequency Port (High Band, e.g. 2400-2500 MHz band on 2R450G diplexer). 50 Ω single-ended RF port; presents high impedance out-of-band so it does not load the Common Port at low band frequencies. |+| 6 | GND | passive | Ground pad.
