Technology (InGaP HBT)

High Efficiency/Linearity Amplifier

The MMA20312BV is a 2--stage high efficiency, Class AB InGaP HBT

amplifier designed for use as a linear driver amplifier in wireless base station

applications as well as an output stage in femtocell or repeater applications. It

is suitable for applications with frequencies from 1800 to 2200 MHz such as

CDMA, TD--SCDMA, PCS, UMTS and LTE at operating voltages from 3 to 5 V.

The amplifier is housed in a cost--effective, surface mount QFN plastic package.
