MEC model J70B-529 is a WR137 Band Pass Filter with finite transmission
zeros. It covers one of the communication tri-bands commonly used for satellite up-link
and down-link communications.
This design features copper construction which helps to minimize losses
– the insertion loss is just 0.5 dB. Flanges are aluminum to avoid incompatibility of
dissimilar metals in an aluminum waveguide system installation. The filter has external
aluminum support brackets to aid mechanical rigidity. There are two reject bands with
ultra sharp rejection skirts and high attenuation. Two notch filters are used to achieve
out of band rejection of 100 dB @ Fc+2%.
