General Notes:
1. Units in the JPP-21R 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. Differential
drive allows easy interface with ECL/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.
