PIN DESCRIPTION

Pin 1 GND

Connect to common ground-plane.

Pin 2 RF OUT

For connection to external antenna. Output impedance is 50

Ω.

Pin 3 Vcc

Positive supply pin, supply voltages from +5.9 to +9 volts may be

used.

Pin 4 GND

Connect to common ground-plane.

Pin 5 DATA IN

Analog or digital input. Should be driven by the same supply

voltage as the module. Usually interfaced with a CMOS logic

level device. Should never exceed Vcc.

PHYSICAL PACKAGING

The transmitter is packaged as a hybrid SIP module with five pins spaced 0.1

in. on center.The SIP package allows easy accommodation of both horizontal

and vertical mounting requirements into a highly compact package. Its leaded

design allows for easy prototyping and simple integration into through-hole

and surface-mount designs. If the module will be bent and laid flush on the

circuit board, a pad of silicon or other adhesive should be used to hold it in

place.

WHAT EXTERNAL COMPONENTS ARE REQUIRED ?

The RM Series transmitter requires only a supply voltage, an external antenna

and analog or digital input. Production adjustment or tuning is not required.
