Weight, nominal: 2.2 oz (65 g) Operating Temp: -- 55° to + 85°C NOTES: 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over millimeters. General Notes: 1. Units in the JTM-2A series of Quadraphase Modulators are composed of two biphase modulators with TTL drivers, a 90° quadrature hybrid and an inphase 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. 3. Units in the JTM-2A series are available with center frequencies from 10 to 1000 MHz and having a minimum b……
