KH-2012-HM1

Shenzhen Kinghelm Elec · Antennas · 0805

KH-2012-HM1 from Shenzhen Kinghelm Elec, 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 INPUT passive RF feed terminal. Connect through the recommended matching network (1.5 pF series, 0 ohm inductor, 0.7 pF shunt on the evaluation board) to a 50 Ohm transmission line driving the 2400-2500 MHz Bluetooth/Wi-Fi radio. Central frequency 2450 MHz, VSWR <= 2.0.
2 NC passive No electrical connection. This terminal is a mechanical/solder anchor pad only; it should be left floating or tied to a non-signal pad per the PCB layout guide. Do not connect to ground or RF trace.
