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.
