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.
