Operating Temperature: -- 55° to +85°C Other frequency bands: Available options General Notes: NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over millimeters. 3. Weights are nominal on all outlines. 1. The QHM-2M and QHM-3M series of quadrature hybrid couplers covers 500 MHz to 12.4 GHz in octave and multi-octave bands, respectively. 2. These units have been designed using miniature stripline construction to achieve high isolation and low VSWR. They may be used in a wide variety of applications requiring -3 dB power division either in-phase or in phase quadrature (or both). Such signals are often required in mixers, modulators and phase shifters among others. 16Apr96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
