SA58646BD - UHF 900MHz transceiver

Download the SA58646BD datasheet PDF. This datasheet also covers the SA58646 variant, as both devices belong to the same uhf 900mhz transceiver family and are provided as variant models within a single manufacturer datasheet.

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 MHz to 928 MHz full-duplex radio.

Key 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. 2. Features I RF RX (single frequency conversion FM receiver): N Integrated LNA N Image reject mixer N FM detector at 10.7 MHz including an IF limiter, a wide band PLL demodulator, an output amplifier and a RSSI output N Carrier detec.

SA58646 UHF 900 MHz 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 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. 2.
