Modulation Sequence
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.
