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-25L series features an in-circuit, voltage controlled phase balance that allows fine adjustment of phase. This feature provides accuracy
not previously attainable in a comparably small package. In addition, the voltage controlled phase balance input facilitates closed loop, servo
operation using the phase adjustment input as feedback.
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.
