General Notes:
GENERAL SPECIFICATIONS
1. Units in the JTF-2F series of Quadraphase Modulators are
composed of two biphase modulators with TTL drivers, a 90°
quadrature hybrid and an in-phase power combiner.
Impedance: 50 W nom.
RF Input Level:
0 dBm nom.
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.
3. Units in the JTF-2F series are available with center frequencies
from 10 to 1000 MHz and having a minimum bandwidth equal to
10% of the center frequency.
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 applications
requiring the highest reliability.
