VECTOR I&Q MODULATOR
For further iformatin contact
MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531
General Notes:
1. A vector modulator is used to phase modulate an
RF carrier with complex analog signals.
2. Merrimac Vector Modulators consist of a
quadrature hybrid and an in-phase power divider.
3. Units in the VMM-2D series are capable of
modulating the carrier at up to 10% of the RF
bandwidth.
4. These units comply with 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.
