RF Micro Devices has announced the availability of the RF6280 3G transmit system, a flexible 3G multimode solution designed to simplify and accelerate implementation of multiband and multimode 3G handsets and mobile device platforms.
The system supports all major WCDMA frequency bands and is comprised of a front end power management IC optimised 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, multiband power amplifier module (capable of supporting Bands I, II, III, IV, V, VI, VIII, IX). The centrepiece of the system is the RF6280 front end power management IC, which combines a low-noise, high efficiency DC to DC converter with embedded hardware control algorithms to enable high efficiency, enhanced performance and ease of use.
The RF6280 utilises analog bias control and patent-pending DC to DC conversion technologies to intelligently and dynamically control PA operating conditions. Enabling mode-optimised 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 for device manufacturers.
By leveraging the broadband characteristics of the dual-band RF6285, RFMD's 3G transmit system greatly simplifies the implementation of multimode, multiregion 3G handset platforms. In addition, by leveraging a balanced (quadrature) PA architecture, the 3G transmit system provides improved total radiated power (TRP) and specific absorption rate (SAR) performance, eliminating the need for costly RF isolators and simplifying multiband platform implementation.
