Avago Technologies’ Fifth Generation of CoolPAM Power Amplifiers Designed for Asian Mobile Carriers’ New Talk Time Requirements

CoolPAM Power Amplifiers for Japan CDMA and Cell Band CDMA Markets Increase Talk Time by 30% Over Conventional Power Amplifiers

SAN JOSE, Calif., December 15, 2008

Avago Technologies, a leading supplier of analog interface components for communications, industrial and consumer applications, today announced that its two power amplifiers based on the fifth generation of CoolPAM technology comply with the new talk time requirements defined by major Asian mobile carriers. Avago’s ACPM-7822, which supports Japan CDMA band, and ACPM-7824, which supports CDMA cell band, improve consecutive usage time for mobile handsets by the active bypass PA technology in CoolPAM. This fifth generation of CoolPAM improves power efficiency in the low output power range.

As cellular coverage in urban and suburban networks improve, particularly in Japan and Korea, the statistical probability profile of handset output power has shifted to levels lower than the standard profile set by the CDG (CDMA Development Group). As a result, handsets tend to operate more often at lower power output levels. Improved efficiency at these lower power levels will increase talk time.

To take advantage of these newer networks, multiple Asian mobile markets have set new talk time profile requirements. The fifth generation of CoolPAM power amplifiers is uniquely designed to support high, mid and active-bypass power modes and addresses these requirements. CoolPAM’s innovative switchless design enables the power amplifier to consume very low quiescent current levels and operate in active bypass mode at up to 11 dBm. The ability to operate at multiple power modes significantly lowers the average current of CDMA transmitter usage and thus extends battery life by as much as 30% over conventional power amplifiers.

Avago’s ACPM-7822 and -7824 are housed in a compact 4 x 4 mm package with one RF input port to simplify handset layout design. These amplifiers are mainly targeted for the Japan and Asia Pacific CDMA handset markets, such as China, Korea and India. Avago’s ACPM-7351 is also based on the fifth generation of CoolPAM and is ideal for the Japan market because of its support of Band 0 and 6 (IMT2000) cellular bands.
