The QHF-6L series of 3 dB quadrature hybrids covers ultra-wide bandwidths using six or more cascaded hybrid sections in a single low profile, hermetic package. This technique results in bandwidth ratios as high as 125:1 making this series ideal for all wide band applications. 1. Tolerance on 3 place decimals ±.010(.25) except as noted. 2. Dimensions in inches over millimeters. 3. Dimension marked with * apply only at body. 4. All unmarked pins are case ground. 22Feb96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
