WCDMA Power Amplifiers

Tue, 04/04/2006 - 8:15am

ANADIGICS introduces its third generation High-Efficiency-at-Low-Power (HELP3™) wideband CDMA (WCDMA) power amplifiers (PAs) (the AWT6273, AWT6278, AWT6279). The amps offer low power consumption and provide full compliance with High Downlink Packet Access (HSDPA) requirements, enabling ultra-fast multimedia access, while extending battery life. ANADIGICS' PAs use the Company's exclusive InGaP-Plus™ technology, which integrates bipolar and field-effect transistor (FET) devices on the same InGaP GaAs die. Through selectable bias modes, the PAs achieve optimal efficiency across the low-range and mid-range output power levels. The PAs provide low quiescent currents of 7 mA without an external DC/DC converter. They also incorporate a built-in reference voltage generator, eliminating the need for external regulators.
