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 many 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.
