C-Band Interference Suppression Filter

This low loss, light and robust 3.7 GHz to 4.2 GHz C-Band band-pass filter efficiently suppress strong out of band interference, caused by navigational communications (radar), as well as many types of other terrestrial interference, strong rejection of unwanted spurious spectrum below and above the pass-band frequency range from DC to lower Ku-band. The filter also practically eliminates transmit (uplink) band so a separate band pass filter is not needed.

Ridged Evanscent - mode filters

These low-loss, low power, miniature evanescent-mode band-pass or harmonic filters could be used in applications where filter size and weight are critical, primarily for Ku-Band (up to 20GHz) frequencies and bellow. The filter shown bellow is a 9-poles ridged evenescent-mode filter with direct transforming via resonant windows. Shorter and ligher than conventional filters of this type.

Waveguide Band-Pass Cavity Filters

These high-Q, high-power, low-loss filters find numerous applications ranging from wide bandpass filters, up to 20% of the central frequency, to ultra-narrow, less then 1% (notch) filters. These filters are manufactured from aluminum, silver plated. Temperature stable versions, using more stable materials are available. Choice of customer - defined waveguide flanges (choke, cover, hermetic). Optional coaxial interface, customer-defined or standard. The filter shown bellow is WR62 band-pass cavity filter.

Harmonic Rejection Filters

These heavy-duty, Ultra High Power (up to 10% of appropriate waveguide power handling), low insertion loss, sharp roll-off filters with compact size and llightweight could be an ideal solution in many applications. Two Ku-Band harmonic regection filters are shown bellow.
