MITEQ’s Model FMX-079149 five-output frequency multiplexer precedes the second IF down conversion stage in a
low earth orbit-based millimeter-wave radiometer. In combination with second IF downconverter, the system
provides maximally flat frequency response over the bands of interest, high linearity of output power to input power,
and high isolation between the frequency bands of interest as well as from other undesirable signals. In addition,
this high reliability, spaceborne integrated assembly is optimized for small size, low power consumption, lightweight,
and excellent thermal stability of operation.
