Power-saving amplifier covers four bands
Power amplifier is designed to meet all requirements for GSM/GPRS and Edge operations in dual-, tri- or quad-band handsets based on Qualcomm's WCDMA, HSPA chipsets.
Anadigics has developed the AWE6174 quad-band Polar Edge power amplifier (PA) module for 3G wireless handsets and equipment "Our company continues to expand its portfolio of compact, high efficiency PA products for 3G and 4G wireless communications", says Ali Khatibzadeh, PhD, Senior Vice President and General Manager of Wireless Products at Anadigics

Power amps cut current consumption in half
New power amplifiers greatly reduce overall power consumption
"The introduction of our new AWE6174 Polar Edge PA once again establishes a new performance benchmark in power consumption for handsets and modules in the 3G marketplace".
Anadigics' new Polar Edge PA is designed to meet all requirements for GSM/GPRS and Edge operations in dual-, tri- or quad-band handsets based on Qualcomm's WCDMA, HSPA chipsets and their latest generation transceivers.
The AWE6174 Polar Edge PA includes separate amplifiers for GSM850/900 and for DCS/PCS bands which are optimised for high performance in both GMSK and 8PSK modes in a 6 x 6mm package that is 25% smaller than current generation Edge PA modules.
An internal reference voltage and integrated power control scheme for simplified GMSK operation make production calibration faster and easier and reduce the number of external components required.
"The unique device architecture in our new AWE6174 Polar Edge PA gives handset designers the option of using an external DC/DC convertor to modulate the amplifier bias voltage and reduce current consumption at backed off output power", says Joe DeMoura, Anadigics Edge Product Line Manager.
"Using a third-party DC/DC convertor in this way can reduce current consumption by half at medium output power and greatly increase battery life and talk time".
The AWE6174 incorporates Anadigics' proprietary InGaP-Plus technology for state-of-the-art reliability, temperature stability and ruggedness.
The PA is manufactured using a material set consistent with the European Union's RoHS Directive.
Product sampling of the AWE6174 amplifier is scheduled for the end of Q1 2008.
