General Notes:
1. I & Q networks are integrated devices that produce two quadrature-phased,
equal amplitude signals when fed RF and LO signals.
2. Comprised of standard components, these units are optimized for high accuracy
at a specified LO frequency and maintain specified performance across a
bandwidth of 10% of the LO frequency.
3. 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 data ports.
4. Merrimac I & Q networks comply with the relevant sections of MIL-M-28837
and can be supplied screened for compliance with additional specifications for
military and space applications requiring the highest reliability.
