Atmel Announces High-Efficiency RF SiGe Power Amplifier for 2.4-GHz ISM and Bluetooth Systems.Business Editors/High-Tech Writers HEILBRONN, Germany--(BUSINESS WIRE)--Oct. 25, 2001 Atmel(R) Corporation (Nasdaq:ATML ATML Automatic Test Markup Language ATML Automated Test Markup Language ) announced today a highly integrated power amplifier for the radio portion of Bluetooth(TM) systems. The new T7023 provides outstanding power-added efficiency (PAE). It is manufactured in Silicon-Germanium (SiGe) technology and is therefore much more cost-effective than conventional Gallium-Arsenide (GaAs) power amplifier solutions. The new power amplifier is designed for 2.4-GHz-ISM (see footnote 1), Bluetooth (class 1), data, HomeRF DECT (Digital Enhanced Cordless Telecommunications) A cordless phone standard mostly used in Europe; however, DECT 6.0 is increasingly used worldwide. The first DECT standards were introduced by ETSI in 1992, and DECT phones have been used as cordless home phones as , proprietary radios and WLAN See wireless LAN. WLAN - wireless local area network FHSS (Frequency Hopping Spread Spectrum) See spread spectrum. (see footnote 2) applications. In Bluetooth systems, the new device helps to boost the operation range beyond 100 m. The power amplifier achieves an output power of +23 dBm/ 3 V at a gain of 25 dB. A ramp-up signal from a Bluetooth transceiver can even reduce the T7023's gain to -17 dB. As required by the Bluetooth specification, the ramp-up signal also prevents an over swing of the output power by a defined, slow switch-on. Due to the ramp-control feature and a very low quiescent current, a switch transistor for the supply voltage is not required. This simplifies the design, saves external components compared with other solutions, and thus reduces production costs. The device provides an outstanding PAE value of up to 45% at 2.4 GHz. Therefore, the current consumption is very low (165 mA). Switching to standby mode helps to even further reduce the current consumption to less than 10 microampere microampere Cardiology A unit of electric current—one millionth of an ampere–for measuring very small electric currents; most pacemakers draw 10–30 µAmp continuously from a battery . Also, due to the excellent PAE value, system costs are lower than with conventional GaAs solutions, as fewer external components are required. "Extremely high power efficiency and thus low current consumption and lower costs than GaAs solutions -- these are the outstanding benefits that make our new product a milestone for advanced Bluetooth applications," stated Udo Tillmann, Marketing Manager for the Bluetooth RF solution at Atmel Wireless & Microcontrollers Division. Samples of the T7023 in small MLP (Meridian Lossless Packing) The compression technique used in DVD-Audio that provides the highest audio quality. It delivers two channels at 192 kHz with 24-bit samples or six channels at 96 kHz. 16 (4 x 4 mm) packages are available now. To support the design-in, Atmel provides a design kit including reference design, design guide and RF board. Pricing for the T7023 starts at $1.01 (at 10 k).
