Specifications and Ordering

Our designs are built onsite and upon request. We tailor each order through our sales engineers to better serve your purchase.


Description

QFH High Pass Filters provide sharp skirt selectivity and high rejection levels for frequencies below their cutoff frequency. They have minimum insertion loss in the pass band.  We offer these filters in seven waveguide bands covering 18 – 110 GHz. Furthermore, we can custom design their rejection characteristics to meet specified subsystem requirements.

The filter length depends on the rejection level and skirt selectivity. Please contact sales@quinstar.com for mechanical outline dimensions.

Applications

Applications for QFH include rejecting lower sideband or image band in receivers and eliminating high power signals at lower frequencies below the applicable signal band. Additionally, these filters can eliminate local oscillator leakage or spurious signals by limiting the band.

Further, QFH can be combined with QFL Low Pass Filter to produce a band pass filter with very broad pass band.
