GENERAL DESCRIPTION

The AD6402 is a complete transceiver subsystem for use in high bit rate radio systems employing FM or FSK modulation. It is optimized for use in time domain multiple access (TDMA) systems with communications rates of approximately 1 MBPS. The AD6402 integrates key functions, including VCOs and a low drop-out voltage regulator. The AD6402 operates directly from an unregulated battery supply of 3.1 V to 4.5 V and provides a regulated voltage output which can be used for VCO supply regulation on a companion RF chip such as the AD6401.
