High Gain Driver Amplifier 50MHz - 2GHz

Currently Viewing:

MGA-31389 is a 0.10W high gain Driver Amplifier MMIC that serves applications from 50 MHz to 2.0 GHz, housed in a SOT-89 standard plastic package.

It is one of the Avago gain blocks family that feature high linearity, high gain, excellent gain flatness and low power dissipation. MGA-31389 is a 0.10W Gain Blocks solution that is optimized for frequency and delivers superior RF performance. There are 2 devices in this High Gain 0.10W Gain Blocks family. The MGA-31389 serves applications from 50 MHz to 2.0 GHz while MGA-31489 covers 1.5 GHz to 3.0 GHz, thus covering all the major cellular bands — GSM, CDMA, and UMTS — plus next generation LTE bands.

A common footprint and PCB layout allows a single design to support multiple frequencies and geographic markets with a choice of output power. The devices also feature high gain which can reduce the total number of RF stages needed.
