Miniature Attenuator Pads

M.E.C.’s miniature attenuator pads feature ultra-flat frequency response and very low VSWR bundled into extremely short flange-size packages.  Typical attenuation flatness over the full waveguide band is ±0.2 dB (±0.3 dB max.), with typical VSWR of 1.10:1 (1.15:1 maximum).  These compact units are available in 1 dB steps from 1 to 10 dB and are ideal for inclusion in systems where length is critical.  These parts have aluminum housings, are chromate conversion finished per MIL-C-5541, Class 3, and painted with gray epoxy enamel on external, non-mating surfaces.
