Analog - New 3G transceiver for femtocell basestations Published Dec 16 2008 [Printer friendly version] [Email article to a friend] [More Semiconductor articles] For 3G femtocell basestations that support the UMTS (universal mobile telecommunications system) wireless interface standard for home and office wireless infrastructure equipment, the ADF4602-1 transceiver has been introduced by Analog Devices .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 seen as ideal for high-performance 3G femtocells providing cellular FMC (fixed mobile converged) services. With a receive sensitivity of better than -113dBm, 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 3.3V supply, the ADF4602-1 transceiver typically consumes 50mA in receive mode and 50mA to 100mA in transmit mode, says the company. Free Sample.
