General Notes:
GENERAL SPECIFICATIONS
1. Units in the JPP-21S 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:
2:1 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. 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
