1. General description
2. Features
The SA58646 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 902 MHz to 928 MHz full-duplex radio. The SA58646 may be used in a UHF
push-to-talk walkie-talkie or in a UHF to 900 MHz data transceiver. The SA58646 is a
pin-compatible derivative of the UAA3515 with advanced features.
This IC integrates most of the functions required for a half-duplex or full-duplex radio in a
single integrated circuit. Additionally, the programmability implemented reduces
significantly external components count, board space requirements and external
adjustments.
