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 IQP-25S 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.
