General Notes:
1. Single Sideband Modulators are integrated
networks composed of an in-phase power
divider, two double balanced mixers and two
90°quadrature hybrids. The primary function of
the circuit is to amplitude modulate a carrier such
that all the energy is in either the upper or lower
sideband.
2. These units are especially useful in modulator
applications where the desired and undesired RF
sidebands are so close in frequency that it is not
practical to use a bandpass filter to separate
them or where minimum group delay is required.
3. By vector subtraction, the undesired sideband
is canceled within the unit (internally terminated)
and the desired sideband is reinforced at the
output. The level of cancellation is usually
expressed as sideband rejection ratio in dB.
4. The schematic diagram shows how the
desired receiver signals from the two mixers are
combined in-phase at the real (RF/LO) port,
while the undesired spurious signals cancel each
other out. At the image port the reverse occurs
and the unwanted sideband signal is absorbed
by the load resistor. (Continued, next page)
