Nuvotronics has developed an innovative SMT filter solution that deliver excellent image rejection performance in an ultra-compact form factor. Filters developed using this technology are up to 90% smaller than traditional waveguide solutions, require no tuning, have low insertion loss and can achieve 50–60 dB of image rejection.
Key Features of New SMT Image Reject Filters
Up to 90% Size Reduction – Traditional waveguide filters are bulky and heavy; Nuvotronics image-rejection filters are ~10.14 x 4.0 x 1.1 mm.
Uncompromised Performance – Matches waveguide performance with 50–60 dB rejection and low passband insertion loss across the Ka-band.
Get to Market Faster, with Easy, Lower Cost Integration – Industry-standard SMT design eliminates transitions between circuit boards and waveguide, repeatable performance out of the box—no tuning needed.
More Value – End customers get smaller, lighter terminals, and same rejection rates, while OEMs save on design, assembly, and testing.
The table below provides a list of available SMT image-reject filters, including key electrical and mechanical specifications to support quick comparison and selection for specific application requirements.
