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-2B and -20B series use both
lumped element circuits and distributed
circuit technologies for high performance
in a proven flatpack design.
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.
