Reference Design Available For Cool-Running Power Amplifiers

July 25, 2006
The CoolPAM modules from Avago consume less battery power in multimode mobile devices.

The CoolPAM power amplifier modules are now incorporated into a reference design from a leading W-CDMA chipset supplier, according to Avago Technologies. The modules offer extended "on" time for multimode third-generation mobile telephones, data cards, PDAs, and other mobile devices, Avago says. The new reference design incorporates the ACPM-7311 for UMTS800 (band 5, 824 to 849 MHz), the ACPM-7331 for UMTS1900 (band 2, 1850 to 1910 MHz), and the ACPM-7381 for UMTS2100 (band 1, 1920 to 1980 MHz) The modules reduce battery power consumption without the need for a dc-dc converter.

Besides W-CDMA UMTS/GSM/GPRS/EDGE networks, the reference design supports High-Speed Downlink Packet Access (HSDPA) service. The devices come in a 10-pin, 4-mm by 4-mm by 1.1-mm surface-mount modules designed to ensure high thermal conductivity, which minimizes temperature rise and improves reliability. They are fabricated with an advanced InGaP heterojunction bipolar transistor MMIC technology. The modules run on 3.2 to 4.2 V and include 50-ω input and output matching networks for simple integration. A control pin is included to set operating parameters for the highest efficiency when operating at low output power levels.
