Avago adds five PAs to CoolPAM range for UMTS handsets and datacards

Avago Technologies of San Jose, CA, USA has added five new CoolPAM power amplifiers (PAs) to its product portfolio for Universal Mobile Telecommunications (UMTS) band handsets and datacard applications.

The ACPM-73x2 series is based on Avago’s fifth-generation CoolPAM circuit technology, which provides what is claimed to be one of the longest talk times among existing power amplifiers (with very low quiescent current of about 3mA). The use of InGaP hetero-junction bipolar transistor (HBT) monolithic microwave integrated circuit (MMIC) technology provides temperature stability and ruggedness.

The PAs are self-contained, fully matched 10-pin surface-mount modules in a thin 0.9mm x 4mm x 4mm form-factor package that incorporates internal 50 ohm input and output matching networks.

The ACPM-73x2 PAs are available in the following UMTS bandwidths and linearity output power requirements:

• band 1: ACPM-7382 (up to 28.25dBm);

• band 2: ACPM-7332 (up to 29.00dBm);

• band 4: ACPM-7392 (up to 28.40dBm);

• band 5: ACPM-7312 (up to 28.25dBm);

• band 8: ACPM-7372 (up to 28.75dBm).

The CoolPAM circuit technology supports three-mode power control with Vbp and Vmode (bypass, mid-, and high-power modes). CoolPAM is a stage bypass technology that enhances power added efficiency (PAE) at low and medium power ranges. An active bypass feature has been added to these PAs to enhance PAE further at low output range which helps to extend talk time. The PAs comply with new talk-time requirements defined by most major global mobile carriers.

Pricing starts from $1.50 in 10,000 volumes.
