GENERAL DESCRIPTION

The ML2724 is a fully integrated 1.5Mbps frequency shift keyed (FSK) transceiver that operates in the unlicensed 2.4GHz ISM frequency band. The device has been optimized for digital cordless telephone applications and includes all the frequency generation, receive and transmit functions. Automatically adjusted filters eliminate mechanical tuning. Closed loop modulation eliminates frequency drift and permits practically unlimited TX duration. The transmitter generates a 3dBm FSK output signal.
