(Unregulated
Input)
DC power supply output and decoupling point
for the IF regulator. A capacitor must be tied
between this pin and ground to decouple
(bypass) noise and to stabilize the regulator.
DC digital 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 VCCA supply and greater than or equal to
2.7V. A capacitor must be tied between this
pin and ground to decouple (bypass) noise.

I (Analog)
Receive RF Input. A simple matching network
is required for optimum noise figure. This input
connects to the base of an NPN transistor and
should be AC coupled.

O (Analog)
TX RF open-collector output. 0dBm nominal
output power into a matched load over 5.725
to 5.850GHz range. This output requires a DC
