General Notes:  
GENERAL SPECIFICATIONS  
1. Units in the JPF-21E series of Quadraphase Modulators are composed of  
two biphase modulators, a 90° quadrature hybrid and an in-phase power  
combiner.  
Impedance:  
50 W nom.  
VSWR:  
1.5:1 max.  
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.  
RF Input Level:  
Data Bandwidth:  
0 dBm nom.  
>100 MHz nom.  
Data Signal Levels: Logic 1:+15 mA nom.  
Logic 0:-- 15 mA nom.  
3. The JPF-21E series is available with frequencies from 10 to 1000 MHz for  
special orders.  
4. 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.  
Weight, nominal:  
0.32 oz (9 g)  
Operating Temperature:  
-- 55° to +85°C  
E-Size Flatpack  
NOTES:  
1. Tolerance on 3 place decimals  
±.010(.25) except as noted.  
2. Dimensions in inches over millimeters.  
3. Dimensions marked with * apply only at body.  
4. All unmarked pins are case ground.
