MITEQ’s Model FMX-076212 broadband three-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.
