IFDMLIM-70-10-0.5-7/5 - MITEQ, Inc.

The IFDMLIM series FM demodulators have excellent IF-to-

baseband characteristics in their respective operating bands.

These demodulators receive FM modulated carriers at different

center frequencies and recover the baseband information with

high fidelity. The application of these demodulators are in satel-

lite communications and test equipment.

FEATURES

• Excellent IF-to-baseband characteristics

• Excellent baseband frequency response

• Wide deviations
