GENERAL SPECIFICATIONS Coupling: Impedance: CW Input: Operating Temperature: -- 3 dB nom. 50 Ω nom. 1 Watt max. -- 55° to +85°C General Notes: NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over millimeters. 1. The QHM-4R-G series covers 500 MHz to 26.5 GHz using an advanced stripline design for high isolation and low loss. 2. Signals applied to any port will split equally between the opposite pair with the adjacent port remaining isolated. The phase relationship is 0° to the port directly opposite and --90° to the port on the diagonal. 3. These units comply with MIL-P-23971 and can be supplied screened for compliance with additional specifications for military and space applications requiring the highest reliability.
