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 IQG-20E is specially tailored for high accuracy at a specified LO frequency.
It maintains the minimum specified performance across a band equal to 10% of
the LO frequency.
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.
RF and Video Bandwidths are typically much greater than specified.
E - Size Surface Mount
NOTES:
1. Tolerance on 3 place decimals
±
.010(.25) except as noted.
2. Dimensions in inches over millimeters.
3. All unmarked pins are case ground.
