Description
M/A-COM’s MA4EX900L-1226 is a silicon monolithic
double balanced low barrier mixer in a low cost surface
mount 8 lead plastic MSOP package. The die uses
M/A-COM’s unique HMICTM silicon/glass process to
achieve low loss passive elements while retaining the
advantages of low barrier silicon Schottky diodes.
Applications
These mixers are well suited for high volume wireless and
cellular applications where small size and repeatability are
required. Typical applications include frequency
conversion, modulation, and demodulation for receivers and
transmitters in both portable cellular and base station
applications.
