Tolerance on 3 place decimals ±.010(.25) except as noted. 2. Dimensions in inches over millimeters. 3. Dimensions marked with * apply only at body. 4. All unmarked pins are case ground. General Notes: 1. The QHF-22A series covers 5 to 300 MHz using a special lumped element design to minimize package size and cost. This series features a low 0.15" profile package suitable for applications where an ultra-miniature package is essential. The 0.385" by 0.5" flatpack which houses these 3 dB Quadrature Hybrids is suited to both terrestrial and aerospace applications where inherent package reliability and hermeticity are essential. 22Feb96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
