Anadigics 公司的AWT6241 是HELP3TM UMTS/TD-SCDMA線性功率放大模塊,采用InGAP HBT技術,單模式控制輸入,工作頻率在1880-1920MHz和2010-2025MHz.工作電壓從3.2V到4.2V, POUT = +27.5 dBm的效率為28%,主要用在TD-SCDMA 1.8/2.0頻段以及 UMTS/WCDMA IMT 2.1 GHz的無線手機和數據設備.本文介紹AWT6241主要特性,方框圖和典型應用電路.
AWT6241: HELP3TM UMTS/TD-SCDMA Linear Power Amplifier Module
The AWT6241 HELP3TM PA is a next generation product for UMTS handsets. This PA incorporates ANADIGICS’ HELP3TM technology to provide low power consumption without the need for an external voltage regulator or DC/DC Converter. The AWT6241 is manufactured on an advanced InGaP HBT MMIC technology offering state-of-the-art reliability, temperature stability, and ruggedness. There are two operating modes for optimum efficiency at high and medium/low power output levels with a single mode input. A shutdown mode with low leakagecurrent increases handset talk and standby-time. The self-contained 3 mm x 3 mm x 1 mm surface mount package incorporates matching networks optimized for output power, efficiency, and linearity in a 50 Ω system.
AWT6241主要特性:
• InGAP HBT Technology
• Single mode control input
• Internal Voltage Regulator eliminates need for external Reference Voltage (VREF)
• Low Leakage Current in Shutdown Mode: <1 mA
• Optimized for a 50 V System
• Low Profile RoHS Compliant Package, 250 8C MSL-3
UMTS/WCDMA
• 42% @ POUT = +28.5 dBm
• 26% @ POUT = +17 dBm (without DC/DC Converter)
• Low Quiescent Current: 8 mA (in low power mode)
• HSDPA Compliant (no backoff required)
TD-SCDMA MODE
• 38% @ POUT = +27.5 dBm
• 22% @ POUT = +16 dBm (without DC/DC Converter)
AWT6241應用:
• Wireless Handsets and Data Devices for
• UMTS/WCDMA IMT 2.1 GHz band
• TD-SCDMA 1.8/2.0 GHz bands
