General Notes:
1. Units in the JTP-2S series of Quadraphase Modulators are composed of two biphase modulators with TTL
drivers, a 90擄 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.
3. Units in the JTP-2S series are available with center frequencies from 10 to 1000 MHz and having a minimum
bandwidth equal to 10% of the center frequency.
4. Merrimac Quadraphase Modulators comply with the relevant sections of MIL-M-28837 and may be supplied
screened for compliance with additional specifications for military applications requiring the highest reliability.
