Avago Technologies has announced five new CoolPAM power amplifiers for use in UMTS band handsets and datacard applications. The new ACPM-73x2 series of PAs are based on Avago’s fifth generation CoolPAM circuit technology which provides one of the longest talk times among existing power amplifiers with very low quiescent current at about 3mA.

  The ACPM-73x2 PAs are fully matched 10-pin surface mount modules designed for UMTS Bands 1, 2, 4, 5 and 8, and meet a wide range of stringent UMTS linearity requirements and output power ranges.  Moreover, the 4 mm X 4mm form factor package is self contained and incorporates 50 ohm input and output matching networks that comply with new talk time requirements defined by most major global mobile carriers.

  The CoolPAM circuit technology incorporated in these new PAs from Avago supports three power modes: bypass, mid-, and high-power modes. CoolPAM is a stage bypass technology which 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.
