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.
