TECHNICAL DESCRIPTION / APPLICATION
I&Q Networks are integrated devices that produce two quadrature-phase, equal amplitude signals when fed
RF and LO signals. Comprised of standard components, these units are optimized for high accuracy at a
given LO frequency and maintain specified performance across 10% of the LO bandwidth. Merrimac I&Q
Demodulators comply with the applicable sections of MIL-M-28837 and may be supplied screened for com-
pliance with additional specifications for military and space applications requiring the highest reliability.
