Specifications and Ordering
Our designs are built onsite and upon request. We tailor each order through our sales engineers to better serve your purchase.
QuinStar offers QNF Band-Reject and Notch Filters at any rejection frequency in the 18 – 185 GHz range. QNF is a selective filter that attenuates signals in a specific frequency band, passing the signals above and below this band. We designed QNF to deliver high rejection coupled with low insertion loss over the pass band.
We customize the filter’s performance to suit the application’s specific attenuation need. The insertion loss depends on the separation between the rejection frequency and the pass band, and the amount of rejection required. Very large rejection (attenuation) over a relatively narrow frequency range virtually eliminates high-power signal (or interference signals) from the band. QuinStar can also design and produce harmonic-reject filters for specific systems or equipment to comply with regulation requirements.
Rejection requirements largely determine the mechanical dimensions and performance characteristics.
These filters eliminate harmonics and known interference frequencies particularly well in communication and plasma diagnostic receivers and radars.
