San Jose, Calif. Avago Technologies has introduced a family of power
amplifiers for mobile handsets based on the fifth generation of its CoolPAM technology. The ACPM-7353 supports three power modes: high-, mid- and active-bypass mode, and features industry-low quiescent current levels. These features can lower the average current of CDMA transmitter usage and conserve power consumption, said Avago.
The switchless architecture of Avago's CoolPAM technology is the foundation for providing the high-power efficiency in the power amplifier, which results in an increase in battery life of up to 10% over previous generations. The highly integrated ACPM-7353 supports dual-band frequencies (cellular and USPCS) and offers a simplified power amplifier design with a single RF input port for each band.
In active-bypass mode, the ACPM-7353 consumes very low quiescent current levels (down to 3 mA) with 10 dB gain and power levels up to 11 dBm output power to improve the low-power efficiency of a transmitter.
In addition to the ACPM-7353, Avago introduced three more power amplifiers with active bypass mode: the ACPM-7351 (dual-band IMT2000 and cellular support), the ACPM-7822 (J-CDMA support), and ACPM-7824 (CDMA cellular support). These power amplifiers are available in two form factors. The dual-band ACPM-7353 and ACPM-7351 ship in a 4 x 5-mm module, and the ACPM-7822 and ACPM-7824 are available in a miniaturized 4 x 4-mm module. The design of each new CoolPAM-based power amplifier takes up less space than two discrete power amplifiers combined, according to Avago.
Pricing: Starts at $1.90 in quantities of 1,000 for the ACPM-7353.
Availability: ACPM-7353, ACPM-7351, ACPM-7822 and ACPM-7824 power amps are
