API Technologies designs and manufactures waveguide filters to 40 GHz with peak power level handling of up to 50 kW. The inherent high Q of Waveguide allows for the design of filters with the lowest possible loss.
This FM band notch filter by ComNav is small in size, inexpensive, and available in volume. It covers the DC to 1500 MHz frequency range and is usable to 1600 MHz. It’s ideal for applications involving broadcast colocations and in jamming reduction. Download the datasheet for more information.
The compact Narrow-Band Notch Ceramic Based Filters feature a frequency range from 500 MHz to 3.0 GHz, and are custom designed to achieve notch specification requirement. These ceramic based filters are now available with higher Q materials, superior depth, and tape and reel packaging.
This is a low pass filter for the record books. With the connectors, it measures over 19 “in length. The pass band is 50MHz to 1990 MHz with less than 1dB of pass band insertion loss. It took over 39 poles to meet the rejection requirements of greater than or equal to 80dB at 2140MHz to 3600MHz.
MtronPTI’s TF0112 varactor tuned aviation navigation band preselector improves safety in cross country and landing operations by attenuating interfering signals that might cause a cockpit radio to lose lock on a desired VOR or localizer/glide-slope signal.
The TF series of coaxial/tubular filters by PDI cover the 10MHz to 18GHz frequency range. They’re available in bandpass and lowpass configurations and are ideal for ground-based radar, MRI and NMR systems, airborne and satellite (limited) applications, antenna masts, and other high-power applications.
MtronPTI’s TF0113 Series of Digitally Tunable LC Filters are found within Vehicle Adapter Amplifiers (VAA), and can dynamically manage the RF spectrum for clear, secure information, and enhance its safety features. When handheld and manpack radios are plugged into VAAs, they can reach a range of 40 km or more.
The new line of YIG Tuned Band-Reject Filters is powered by new patent-pending technologies that are closer to achieving the ‘perfect notch’ in band-reject filters than ever before. This new product line offers major performance advantages including increased minimum rejection bandwidths and notch depth at lower frequencies, a reduction in the maximum 3dB bandwidth at higher frequencies, and a reduction in spurious responses across the board.
