MODELS: SYSMM1X4345, SYSMM2X4345 AND SYSMM3X4345
FEATURES
• Low noise figure............... 3.6 dB typical
• High gain ........................... 29 dB typical
• Output 1 dB comp. ........... +7 dBm typical
• Integrated packaging ....... Hermetically sealed
• Integrated LO multiplier
43 TO 45 GHz LOW-NOISE FRONT END WITH LO MULTIPLIER OPTION
The SYSMM3X4345 is an integrated low-noise converter with internal image filtering and LO multiplier. The inte-
grated LO multiplier provides higher front end compression point than would be possible with a passive sub-har-
monic mixer. Internal LO filtering reduces spurious and fundamental LO leakage. All devices are screened to MIL-
STD-883 method 1010 and 1008 prior to hermetic sealing for high reliability. The single piece housing is a robust
mechanical design for ease of use in any system. Waveguide inputs, alternate frequency bands, and quadrature
or image rejection style units are available. Please contact MITEQ.
