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 VMP-2S series are capable of modulating the carrier
at up to 10% of the RF bandwidth.
4. These vector 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.

AVAILABLE OPTIONS
Close tolerance phase and amplitude balance versions are
available in custom designs. Units with lower center frequency
(e.g., 10 MHz to 1 GHz) are available in the VMP-2R series
NOTES:
1. Tolerance on 3 place decimals
±
.010(.25) except as noted.
2. Dimensions in inches over millimeters.
3. Lead dimensions apply only at body.
