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-2R 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 higher
center frequency (e.g.,1500 MHz to 3 GHz) are avail-
able in the VMP-2S series.
