MITEQ’s model 136466 broadband-three output frequency multiplexer precedes the second IF down conversion
stage in a low earth orbit-based millimeter-wave radiometer. In combination with the MITEQ 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.
