General Notes:
1. I & Q networks are integrated devices that produce two quadrature-phased, equal amplitude signals when fed RF
and LO signals.
2. The IQF-24E series I&Q networks are factory adjusted with a reference capacitor at a given LO frequency. Upon
customer installation, the units may be fine tuned as required by selecting an appropriate external capacitor value.
3. Merrimac I & Q networks 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.
