General Notes:
1. I & Q networks are integrated networks that produce two quadrature phased, equal amplitude signals when fed RF and LO signals.
2. The IQM-A series uses lumped element circuits for small size and high performance.
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.
