Broadband Miniature Attenuators RLC Electronics' Broadband Miniature Attenuators offer precision impedance matching and bi-directional handling over the extremely broad frequency of DC to 18 GHz. They are also available 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-C39012. Units can be supplied in standard attenuation values as listed or other values for specific requirements. Three combinations of connectors are available in the standard models.
