RFMD Introduces Smallest Linear PA Module With Integrated Power Detector

Cannes, France -- 3GSM World Congress -- RFMD (RFMD) today introduced the RF5198 high-power, high-efficiency linear power amplifier (PA) module for WCDMA handset applications.

Measuring 3 mm by 3 mm by 0.9 mm, the RF5198 is the world's smallest linear PA module to include an on-chip power detector. By incorporating the power detector technology on-chip, the RF5198 reduces design complexity and streamlines the handset design process, thereby enabling handset manufacturers to quickly bring their advanced products to market.

"We believe RFMD supports more handset manufacturers with WCDMA transmitter solutions than any other company," Konrad Alvarino, general manager of power amplifier products, RF Micro Devices, said. "With its integrated power detector, the RF5198 represents the smallest and most highly integrated WCDMA PA module ever introduced. By leveraging our expertise in process and packaging technologies, we've integrated the power detector functionality into a 3 mm by 3 mm by 0.9 mm form factor. Our new RF5198 PA module provides exceptional WCDMA performance and ease of implementation, thereby enabling our customers to introduce next-generation multimedia handsets more quickly and cost-effectively."

The high-power, high-efficiency RF5198 is a self-contained PA module with 50-ohm 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 3V WCDMA handheld digital cellular equipment in the 1920 to 1980 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 3x3mm 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 calendar year 2005. RFMD will showcase the RF5198 PA module at 3GSM World Congress, February 14-17, in Hall 2 Booth #E32.
