General Notes:
1. Dual I & Q networks are integrated devices that produce two pairs of quadrature-phased, equal amplitude
signals when fed by two IF signals and an LO signal as shown in the schematic above.
2. Merrimac’s IDP-2S series combines two matched circuits in one package. Both lumped and distributed
circuit technologies are used to minimize size and weight while maintaining excellent overall performance.
3. Merrimac’s I & Q networks comply with the relevant sections of MIL-M-28837 and may be screened for
compliance with additional specifications for military and space applications requiring the highest reliability.
