Broadband Fully Integrated Matched Low-Noise Amplifier MMIC

The Avago MGA-21108 is a fully integrated GaAs Low Noise Amplifier, LNA, MMIC for use in the 1.5GHz  to 8GHz band. Broadband performance is achieved with only one external input matching component. Power supply chokes and coupling capacitors are also integrated.

It is housed in a miniature (2.5 x 2.5 x 0.55) mm 8-pin STSLP package.
