- ADI’s ADF4602-1 transceiver paired with mixed-signal front-end and driver amplifiers creates complete UMTS radio that consumes 30% less power and delivers 50% better EVM.

NORWOOD, Mass. (Business Wire EON/PRWEB ) December 1, 2008 -- Analog Devices, Inc. (ADI), a world leader in high-performance semiconductors for signal processing applications, introduced today the ADF4602-1 transceiver for 3G femtocell base stations that support the UMTS (universal mobile telecommunications system) wireless interface standard for home and office wireless infrastructure equipment. The highly integrated direct conversion transceiver incorporates frequency synthesizers, filters and power management circuitry and can be coupled with ADI’s AD9863 mixed-signal front-end and ADL532x and ADL554x driver amplifier families to create a complete UMTS radio. The complete design consumes 30 percent less power and delivers 50 percent better EVM (error vector magnitude) than competing devices while improving data rates and system fidelity in multi-band 3G femtocell base stations.

The ADF4602-1 3G transceiver is ideally suited to high-performance 3G femtocells providing cellular FMC (fixed mobile converged) services. With a receive sensitivity of better than –113 dBm, the front end includes three high-performance single-ended LNAs (low-noise amplifiers), allowing the device to support tri-band applications. The receiver is based on a direct conversion architecture, which is an ideal solution for highly integrated W-CDMA (wideband code division multiple access) receivers and reduces the BOM (bill of materials) by fully integrating all interstage filtering. The single-ended input structure eases interface design constraints and reduces the matching components required for small footprint single-ended duplexers. The transmitter uses an innovative direct conversion modulator that achieves high modulation accuracy with exceptionally low noise, eliminating the need for external transmit SAW (surface acoustic wave) filters. Operating on a 3.3-V supply, the ADF4602-1 transceiver typically consumes 50 mA in receive mode and 50 mA to 100 mA in transmit mode.
