Description
The ACPM-7870 is a linear quad-band / multi-mode power amplifier module for both GMSK and 8-PSK modulation schemes. There are two amplifier chains, one is to support GSM850/900 bands, and the other is to support DCS1800/PCS1900 bands. CoolPAM technology, which is Avago Technologies’ Power Amplifier technology provides extended talk time with extremely low quiescent current and enhanced efficiency at low and medium power modes.
