Ultra Low Noise, High Linearity Low Noise Amplifier

Currently Viewing:

Avago Technologies’ MGA-634P8 is an economical, easy-to-use GaAs MMIC Low Noise Amplifier (LNA) and has Low Noise and High Linearity achieved through the use of Avago Technologies' proprietary 0.25um GaAs Enhancement-mode pHEMT process.

The MGA-634P8 low noise amplifer is the latest addition to Avago’s family of ultra low noise, high gain, high linearity Gallium Arsenide (GaAs) low noise amplifiers, designed to be used as first stage LNA of cellular base station transceiver radio cards, tower mounted amplifiers (TMA), combiners, repeaters and remote/digital radio heads.
