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

QuinStar’s QFL Low Pass filters provide high rejection level and steep skirt selectivity for frequencies above the band edge or corner frequency. Their pass band has low insertion loss over full standard waveguide bands. We offer standard Low Pass Filters in seven waveguide bands covering 18 – 110 GHz. For all standard models, the lower band edge establishes the cut-off frequency of the waveguide. These components have a significantly wide rejection band that covers up to three times the highest pass band frequency.

QFL Applications

Overall, QFL filters work well as harmonic filters and as pre-selectors for receivers. They remove undesirable sideband or spurious signals from converters for receivers and transmitters. These filters eliminate or minimize sub-harmonics, harmonics, and spurious signals in test equipment such as network analyzers and signal generators.

Additionally, a Low Pass Filter QFL and a High Pass Filter QFH can be combined to create a very broad bandpass filter with distinct advantages as a result. Contact us for more information at sales@quinstar.com.
