GENERAL DESCRIPTION
The UAA3515A is a BiCMOS integrated circuit that
performs all functions from antenna to microcontroller in
reception and transmission for both base station and
handset of a 900 MHz cordless telephone set. In addition,
the implemented programming reduces significantly the
amount of external components, board space and external
adjustments required.
