Pin Descriptions

RF GND (pin 1)

RF Ground pin is internally connected to pin 4 (0V) This pin should ideally be connected to the nearest

ground plane (e.g. coax braid, main PCB ground plate etc.)

RF OUT (pin 2)

50

Ω RF antenna output. To achieve best results the antenna impedance must match that of the module.

recommended that a 100nF capacitor decouples the supply rail as close as possible to this pin.

GND (pin 4)

Supply and data ground connection, connected to pin 1.

Data IN (pin 5)

This input has an impedance of 47K

Ω and should ideally be driven by a CMOS logic drive or compatible.

The drive circuitry should be supplied with the same supply voltage as the Tx module.
