RFMD Announces Availability of 3G Transmit System

(Product News, 21 Feb 2008)


RF Micro Devices Inc. (RFMD) has released the RF6280 3G transmit system, a flexible 3G multi-mode solution designed to simplify and accelerate implementation of multi-band and multi-mode 3G handsets and mobile device platforms. RFMD's RF6280 3G transmit system supports all major WCDMA frequency bands and is comprised of a front end power management IC optimized for use with either one or both of two available power amplifier (PA) options: the RF6281 and/or the RF6285. The RF6281 is a dedicated single-band power amplifier module (supporting Band I), and the RF6285 is a flexible dual-path, multi-band power amplifier module (capable of supporting Bands I, II, III, IV, V, VI, VIII, IX). The centerpiece of the 3G transmit system is the RF6280 front end power management IC, which combines a low-noise, high efficiency DC/DC converter with embedded hardware control algorithms to enable best-in-class efficiency, enhanced performance and improved ease-of-use.

The RF6280 utilizes analog bias control and patent-pending DC/DC conversion technologies to intelligently and dynamically control PA operating conditions. Enabling mode-optimized PA efficiency and linearity performance, the RF6280 also ensures maximum efficiency across all power levels, data rates (voice-only to HSPA) and non-ideal load conditions (also known as "antenna mismatch"). This helps extend battery life and significantly reduces average thermal dissipation, both of which are critical metrics to handset manufacturers.
