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.
Bandwidth:
DC to 10% of RF
Output Characteristics
Conversion Loss:
2. The SSP-1R 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.
9 dB max.
3. Units in the SSP-1R 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.
Sideband Rejection: 30 dB min.
Carrier Suppression: 25 dB min.
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.
