RF Micro Devices' PCS CDMA/TDMA Power Amplifier Module Combines Small Size and Ease of Application.ANAHEIM, Calif.--(BUSINESS WIRE)--June 15, 1999-- RF Micro Devices RF Micro Devices (NASDAQ: RFMD) is a manufacturer of integrated circuits, founded in Greensboro, NC, in 1991 by William J. Pratt, Powell T. Seymour and Jerry D. Neal.[1]. , Inc. (Nasdaq:RFMD RFMD RF Micro Devices (NASDAQ) RFMD Rotary Fluid Management Device ), here attending the 1999 IEEE (Institute of Electrical and Electronics Engineers, New York, www.ieee.org) A membership organization that includes engineers, scientists and students in electronics and allied fields. MTT-S MTT-S Microwave Theory and Techniques Society (IEEE) International Microwave Symposium/Exhibition, has introduced the RF3101, a high-power, high-efficiency linear amplifier module ideally suited to 3V digital cellular systems. Manufactured using an advanced GaAs HBT HBT Heterojunction Bipolar Transistor HBT HyCult Biotechnology (Uden, The Netherlands) HBT Hanbury-Brown-Twiss (interferometer) HBT Herring Bone Twill HBT Heflex Bioengineering Test (gallium arsenide heterojunction bipolar transistor The heterojunction bipolar transistor (HBT) is an improvement of the bipolar junction transistor (BJT) that can handle signals of very high frequencies up to several hundred GHz. It is common in modern ultrafast circuits, mostly radio-frequency (RF) systems. ) process technology, the RF3101 is designed for use as the final RF amplifier in 3V PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. and TDMA (Time Division Multiple Access) A satellite and cellular phone technology that interleaves multiple digital signals onto a single high-speed channel. For cellular, TDMA triples the capacity of the original analog method (FDMA). handheld digital cellular equipment, spread-spectrum systems and other applications in the 1850MHz-1910MHz band. Offered in a 5 mm x 6 mm x 1.7 mm LGA LGA abbr. large for gestational age LGA Large for gestational age, see there package, the RF3101 is believed to be the smallest PCS amplifier module in the industry. Both the input and output are matched to 50-ohms internally, and require no additional components externally. "This module represents the first of several new modular products that we have developed for the competitive cellular PA market. With a fully matched module, our customers can reduce their component count and design time," states Victor Steel, product line director of PA Products. "Combined with our single-supply voltage GaAs HBT technology, we are confident that this product provides the best available solution in the market today". The self-contained device delivers 29 dBm linear output power and 24 dB linear gain while operating at 35% linear efficiency. This revolutionary module supports applications such as 3V PCS CDMA cellular handsets, 3V PCS TDMA cellular handsets, spread-spectrum systems, and varied battery-powered portable equipment. A mode select pin allows for increased efficiency at low output powers. Requiring only one positive supply voltage and no external matching components, the RF3101 module eases design and application time. Also included is a power down control pin allowing leakage current of only 1 microamp in the off state. Samples of the RF3101 amplifier module will be available in August of 1999.
