Logic 0: -- 15 mA nom. Weight, nominal: 2 oz (57 g) Operating Temp: -- 55° to +85°C †RF Output and Data Bandwidths are typically much greater than specified. General Notes: 1. Units in the JPM-A series of Quadraphase Modulators are composed of two biphase modulators, a 90° quadrature hybrid and an in-phase power combiner. 2. These devices are generally used in systems to generate QPSK coded signals. The units accept two differential data inputs each of which independently biphase modulates an RF carrier. These are then combined to produce a quadraphase output of 0, 90, 180 and 270 degrees. All units in this series may be ordered with optional integrated TTL drivers. 3. Merrimac Quadraphase Modulators comply with the relevant sections of MIL-M-28837 and may be supplied screened for compliance with additional specifications for military and space applications requiring the highest reliability. NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over millimeters. 14Feb96 |
