900-MHz ISM Band Receiver

Description

The receiver IC U2762B-B is specifically designed for U2781B, a complete ISM RF IC kit is available which fits

cordless telephone applications in the 900-MHz ISM perfectly with AMD’s PhoX controllers AM79C432A

band. It is manufactured using TEMIC’s advanced UHF and AM79C433.

process. The IC consists of a 900-MHz RF amplifier and

mixer, 10.7-MHz IF amplifier, limiter, RSSI, quadrature

Electrostatic sensitive device.

demodulator and comparator for the bit-slicer function.

Observe precautions for handling.

The device features 2.9-V operation. In conjunction with

TEMIC’s transmitter IC U2763B-B and the PLL

Features

Benefits
