MGA-21108
Broadband Fully Integrated Matched Low-Noise Amplier MMIC
Data Sheet
Description
Avago Technologies’ MGA-21108 is a fully integrated
GaAs Low Noise amplier MMIC for use in the (1.5 - 8) GHz
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.
It includes a CMOS-compatible shutdown pin which can
also be used as a variable gain bias pin. The ease-of-use
and broadband performance make the MGA-21108 an
ideal choice as a LNA for multistandard, multiband radio
applications.
