PRELIMINARY ML2721 Low IF Digital Cordless Transceiver GENERAL DESCRIPTION The ML2721 can be used as a single chip digital cordless telephone transceiver or general purpose Frequency Shift Keying (FSK) radio transceiver. It is designed to work in the 902 to 928MHz ISM band under FCC Part 15 regulations. The device integrates all the frequency generation, receive and transmit functions for data rates up to 1.5Mbps. A complete radio only requires the addition of an antenna switch. Micro Linear’s ML2751 is an integrated 100mW power amplifier and receive LNA with transmit/receive PIN diode drivers, and it can be used with the ML2721 for extended range capability. The ML2721 contains a proprietary low IF receiver with all channel selectivity.
