High Gain, High Linearity Active Bias Low Noise Amplifier

Currently Viewing:

Avago Technologies' MGA-14516 is a two stage, easy-to-use GaAs MMIC Low Noise Amplifier (LNA) with active bias.

The LNA has low noise with good input return loss and high linearity achieved through the use of Avago Technologies' proprietary 0.5um and 0.25um GaAs
Enhancement-mode pHEMT process.
