Heterojunction Bipolar Transistor
Technology (InGaP HBT)
High Efficiency/Linearity Amplifier
The MMA25312B is a high efficiency InGaP HBT amplifier designed for
use in 2400 MHz ISM applications, WLAN (802.11g), WiMAX (802.16e) and
wireless broadband mesh networks. It is suitable for applications with
frequencies from 2300 to 2700 MHz using simple external matching
components with a 3 to 5 volt supply.
