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.
