Dimensions in inches over millimeters. 3. Dimensions marked with * apply only at body. 4. All unmarked pins are case ground. 5. External capacitors in the range 1 to 10 pF required. 0.3 dB max. Weight, nominal: 0.32 oz (9 g) Operating Temperature: -- 55° to +85°C † RF and Video Bandwidths are typically much greater than specified. 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-24E series I&Q networks are factory adjusted with a reference capacitor at a given LO frequency. Upon customer installation, the units may be fine tuned as required by selecting an appropriate external capacitor value. 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. 24Oct95 ForfurtherinformationcontactM ERRIM AC /41 Fairfield Pl.,W estCaldw ell,NJ,07006 / 973-575-1300 /FAX 973-575-0531
