Description
M/A-COM's MA4EX950M-1225T is a silicon monolithic
700-1200 MHz double balanced mixer in a low cost
miniature surface mount SOT-25 package. The die uses
M/A-COM's unique HMIC
TM
silicon/glass process to
achieve low loss passive elements while retaining the
advantages of medium 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 in wireless
receivers and transmitters.
