Avago unveils five CoolPAM power amplifiers

The ACPM-73x2 series of PAs are based on Avago's fifth-generation CoolPAM circuit technology, which provides long talk times with a low quiescent current at about 3mA.

Avago's ACPM-73x2 PAs are fully matched 10-pin surface-mount modules designed for UMTS bands 1, 2, 4, 5 and 8.

They meet a range of UMTS linearity requirements and output power ranges.

The 4 x 4mm form-factor package is self contained and incorporates 50ohm input and output matching networks.

These PAs comply with the new talk-time requirements defined by most global mobile carriers.

The CoolPAM circuit technology incorporated in these PAs supports 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 a low-output range, which is intended to help extend talk time.

The PAs are manufactured on advanced InGaP hetero-junction bipolar transistor microwave monolithic integrated circuit technology for temperature stability and ruggedness.

According to the company, they come in a thin 0.9mm package and feature excellent linearity, three-mode power control with Vbp and Vmode and high efficiency at maximum output power.

They are lead free and RoHS compliant.
