General Notes:
1. Single Sideband Modulators are
integrated networks composed of an
in-phase power divider, two double
balanced mixers and at least one 90°
quadrature hybrid.
2. The SSP-2 series is suitable for
applications where the modulating signal is
provided together with one in phase
quadrature to it. This permits operation
down to DC and eliminates the need for a
second 90° quadrature hybrid.
3. Units in the SSP-2 series are suitable
where the desired and undesired RF
sidebands are too close to be effectively
separated with a simple bandpass filter or
where minimum group delay is required.
4. Merrimac Single Sideband Modulators
are available in various package options.
5. Merrimac Single Sideband 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.
