DC power supply decoupling point for

Quadrature Mixer and IF filter circuits. A

capacitor must be tied between this pin

and ground to decouple (bypass) noise

and to stabilize the regulator.

DC power supply decoupling point for IF,

Demodulator, and Data Slicer circuits. A

capacitor must be tied between this pin

and ground to decouple (bypass) noise

and to stabilize the regulator.

DC power supply input to the interface

logic and control registers. This supply is

not connected internally to any other

supply pin, but its voltage must be less

than or equal to the VCC5 supply and

greater than 2.7V. A capacitor must be

tied between this pin and ground to

decouple (bypass) noise.

Receive RF Input. Nominal impedance at

902 to 928MHz is 17-50j Ω with a simple

matching network required for optimum

noise figure. This input is to the base of

an NPN transistor and should be AC

coupled.
