General Notes:  
1. Units in the JPF-21F 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. Units in the JPF-21F series are available from stock with a 1500 and 2500  
MHz center frequency and from 1500 to 3000 MHz for special orders.
