RF Micro Devices Intros RF5198 Power Amplifier Module

March 01, 2005 by Jeff Shepard

RF Micro Devices Inc. (RFMD, Greensboro, NC), a provider of proprietary radio frequency integrated circuits for wireless communications applications, introduced its RF5198 high-power, high-efficiency, linear power amplifier (PA) module for WCDMA handset applications.

Measuring 3 mm x 3 mm x 0.9 mm, the RF5198 is a self-contained PA module with 50 Ω input and output, and is internally matched to obtain optimum power, efficiency and linearity. Manufactured on an advanced third-generation GaAs HBT process, the RF5198 is designed for use as the final RF amplifier in 3 V WCDMA hand-held digital cellular equipment in the 1,920 MHz to 1,980 MHz bands. The RF5198 features a digital control line to lower quiescent current for increased talk time in low-power conditions. Assembled in an ultra-small, low-profile, 16-pin, 3 mm x 3 mm, QFN package, the RF5198 provides enhanced thermal dissipation compared to traditional laminate-based modules.

The RF5198 is currently being sampled to customers and will ramp into mass production in the second quarter of 2005.
