I & Q Modulation Inputs
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 SSF-1E 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 SSF-1E 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.
