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 .
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 detection with programmable threshold N Programmable data amplifier (slicer) phase I Synthesizer: N Crysta.
The SA58646 is a BiCMOS integrated circuit that performs all functions from the antenna to the microcontroller for recep.
