Broadband Miniature Attenuators
RLC Electronics' Broadband Miniature Attenuators offer preci-
sion impedance matching and bi-directional handling over the
extremely broad frequency of DC to 18 GHz. They are also avail-
able in the reduced frequency ranges of DC to 12.4 GHz, DC to
8 GHz and DC to 1.5GHz. These miniature microwave structures
are uniquely constructed resistive film elements combined with
precision connectors meeting the full requirements of MIL-C-
39012. Units can be supplied in standard attenuation values as
listed or other values for specific requirements. Three combina-
tions of connectors are available in the standard models.
