Description

The UAA2062 is a BiCMOS integrated circuit that performs all functions from the antenna to the microcontroller for reception and transmission for both the base station and the handset in a cordless telephone.

UAA2062 integrates most of the functions required for a cordless telephone into a single integrated circuit. The  implemented programming enables the UAA2062 to be used for the CT0 standard in many countries. Additionally, the implemented programming significantly reduces the amount of external components, board space requirements and external adjustments.
