New power amplifier modules from Avago to extend GSM/EDGE handset talk time

Avago Technologies has released the ACPM-7868 power amplifier modules (PAMs). These PAMs target extend handset talk time for GSM/EDGE communication. The new ACPM-7868 PAMs are fully compatible with Qualcomm's chipsets that support linear quad-band GSM/EDGE operation.

The new ACPM-7868 PAMs employ CoolPAM technology to provide extended talktime with low quiescent current i.e. reduced to 8.5 mA typically. The PAMs have two mode control pins that provide four power modes for low band and three power modes for high band. It is also reported that at 29 dBm antenna power where talk time is measured, the technology enables a handset to save current consumption by more than 100 mA compared with conventional power amplifiers.

"Handset manufacturers are seeing strong demand for extended talk time of EDGE," said James Wilson, marketing director for RF and Microwave products at Avago. "Avago's new ACPM-7868 power amplifier modules use our proprietary CoolPAM technology to deliver better power efficiency and help meet these demands."

Avago's ACPM-7868 PAMs feature pre-distortion by chipset for improved linearity and efficiency. The modules incorporate 50 ohm matching networks for both RF input and output. The new power amplifiers are manufactured on advanced InGaP HBT (Hetero-junction Bipolar Transistor) technology.

Package: 16-pin surface mount package with a 5- by 5-mm footprint. The package's 0.9-mm height supports slim handset designs. The devices are lead-free and RoHS compliant

Operating temperature range: -20°C to +90°C

Price: ACPM-7868 GSM/EDGE PAMs: Starts ate US$1.50 for 10,000 pieces
