Description

This is UHF 900MHz transceiver IC. SA58646 UHF 900 MH- transceiver IC Rev. 01 8 February 2007 Product data sheet 1. General description 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 MH- to 928 MH- full-duplex radio. The SA58646 may be used in a UHF push-to-talk walkie-talkie or in a UHF to 900 MH- 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 signi cantly external components count, board space requirements and external adjustments. 2. Features I RF RX (single frequency conversion FM receiver): N Integrated LNA N Image reject mixer N FM detector at 10.7 MH- including an IF limiter, a wide band PLL demodulator, an output ampli er and a RSSI output N.
