Amalfi Semiconductor launched what it claims as the industry's first CMOS-based power amplifier (PA) for GSM/EDGE cellphones.

The AM8901 is part of the company's new Stratos CMOS PA product family for cellphone applications. In addition to this, Amalfi also launched the Stratos AM8801, a CMOS-based power amplifier for GSM/GPRS cellphones. The product family is based on an innovative CMOS silicon architecture called AdaptiveRF that reduces the battery's electrical current requirements in cellphones.

According to Amalfi, the AM8901 will enable manufacturers to deliver phones with greater than 20 percent improvement in usage time, thinner designs and additional functionality, such as mobile TV, MP3 player and video camera. CMOS PAs are also designed to improve manufacturability and lower overall system cost of cellphones.
