Description
50 ohm antenna output.The antenna port impedence affects output power and harmonic emissions.An L-C low-pass filter may be needed to sufficiently filter harmonic emissions.Transmitter ground.Connect to ground plane.Digital data input.This input is CMOS compatible and should be driven with CMOS level inputs.Pins 4 provides operating voltage for the transmitter.VCC should be bypassed with a .01uF ceramic capacitor and filtered with a 4.7uF tantalum capacitor.N
