WCDMA Power Amplifiers
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.
