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-27L series features in-circuit, voltage controlled phase
and
amplitude balance adjustments that allow fine adjustments when the
device is in its normal operating environment. These features provides
accuracy not previously attainable in a comparably small package. In
addition, the voltage controlled phase and amplitude balance inputs
facilitate closed loop, servo operation using the adjustment inputs in the
feedback loops.
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.
