RF Micro Devices Introduces Reduced Footprint PowerStar Quad-Band Power Amplifier Module with Integrated Power Control

2/19/2003 - RF Micro Devices, Inc. (NASDAQ:RFMD), a leading provider of proprietary radio frequency integrated circuits (RFICs) for wireless communications applications, introduced the RF3133, the smallest available quad-band power amplifier (PA) module with integrated power control circuitry.

The RF3133 extends the PowerStar(TM) family of PA modules, which feature power control based on collector control - the industry's leading integrated method of power control for GSM PAs. In addition to the RF3133, RFMD's PowerStar(TM) family includes the second-generation RF3140 quad-band PA module, introduced in November 2002, and the first-generation RF3110 triple-band PA module, introduced in September 2001. The RF3133 features quad-band performance in a small, 7 x 10 mm footprint. All PowerStar(TM) PA modules eliminate the need for directional couplers, detector diodes, power control ASICs and other power control circuitry, while providing handset manufacturers the key benefits of reduced component count, improved production yield, simplified phone calibration and faster time-to-market.

"We are pleased to introduce our third PowerStar(TM) product, featuring improved integration and reduced internal component count," said Joe Grzyb, general manager of power amplifier products at RF Micro Devices. "Utilizing only 70 square millimeters of board space, the RF3133 is the world's smallest PA module with integrated power control. By integrating critical passive components onto our gallium arsenide heterojunction bipolar transistor (GaAs HBT) process technology, we achieved not only a smaller footprint but also a highly precise PA matching network.

"RF Micro Devices is the world's leading manufacturer of power amplifiers, and we have experienced tremendous success with our PowerStar(TM) products, selling more than 10 million units to date. In addition to reduced cost and simplified phone design and manufacturing, our PowerStar(TM) products significantly reduce our customers' engineering time and resources in product test, in some cases by more than 50 percent, thereby accelerating time-to-market. We expect significant interest in the RF3133 and anticipate PowerStar(TM) products will drive GSM/GPRS market share gains in 2003."

The collector control method of power control was developed by design to meet stringent European Telecommunications Standards Institute (ETSI) specifications for transient spectrum and burst timing. Unlike other methods of power control, such as current sensing and power detect, collector control requires no external components and demonstrates minimum variation across temperature, frequency and voltage. As a result, PowerStar(TM) PA modules provide handset customers the most robust and consistent burst timing and transient spectrum performance, which are primary specifications required by ETSI for cell phone full type approval, or FTA.

The RF3133 is designed for use as the final RF amplifier in single- and multi-band GSM, DCS and PCS handheld digital cellular equipment and other applications in the 880 MHz to 915 MHz, 1710 MHz to 1785 MHz and 1850 MHz to 1910 MHz bands. The RF3133 includes a fully integrated silicon CMOS power control loop that meets all spectrum and burst-timing requirements, with 50 ohm input and output terminals. To simplify engineering effort and shorten cycle time, the RF3133 also includes software tools that allow the engineer to instantly calculate ramp profiles, which saves months of development time.

The multi-band RF3133 is offered as part of the POLARIS(TM) TOTAL RADIO(TM) transceiver, which performs the transmit and receive functions of a wireless handset's radio section.

The RF3133 is manufactured using GaAs HBT for power amplification with silicon CMOS used to integrate the power control circuitry. The product is packaged in 7 x 10 mm leadless chip carrier and is available now from RFMD.
