General Notes:
www.DataSheet4U.com
1. I & Q networks are integrated devices that produce two
quadrature-phased, equal amplitude signals when fed by
RF and LO signals.
2. With the addition of an external IF 90° Hybrid, complete
systems are formed that are useful in image rejection and
single sideband modulators.
3. These units are also excellent as phase correlators in
closed loop applications and vector modulator
sub-systems.
4. I & Q networks can also be used in digital systems as a
QPSK demodulator where it recovers two data channels
from the incoming phase information. The QPSK input is
applied to the RF port while the recovered carrier is applied
to the LO port resulting in the two independent data outputs
at the I and Q ports.
5. Merrimac I & Q networks comply with the relevant
sections of MIL-M-28837 and may be supplied screened for
29Apr96
