Pin Name
Description
1
ANT
50 ohm antenna output. The antenna port impedance affects output
power and harmonic emissions. An L-C low-pass filter may be
needed to sufficiently filter harmonic emissions.
2
GND
Transmitter ground. Connect to ground plane.
3
DATA
Digital data input. This input is CMOS compatible and should be
driven with CMOS level inputs.
4
VCC
Pin 4 provides operating voltage for the transmitter. VCC should be
bypassed with a .01uF ceramic capacitor and filtered with a 4.7uF
tantalum capacitor. Noise on the power supply will degrade
transmitter noise performance.
