The ADRF5440 integrates a driver to perform logic functions inter-

nally and provides the user with the advantage of a simplified

CMOS-/LVTTL-compatible control interface. This driver features two

digital control input pins, V1 and V2. The logic level applied to the

control pins determine which RF port is in the insertion loss state

and in the isolation state (see Table 7).
