| IQF-25L Series I&Q NETWORKS 1.5 to 3 GHz / 10 % Bandwidth / In-Circuit, Voltage Controlled Phase Balance / Hi-Rel Hermetic Pkg PRINCIPAL SPECIFICATIONS Model Number IQF-25L-***B LO Frequency, fo, MHz 1500 - 3000 Bandwidth RF Input 10% of fo For complete Model Number replace *** with desired LO Frequency in MHz. GENERAL SPECIFICATIONS RF and LO Input Characteristics Impedance: 50 nom. VSWR: 1.5:1 max. RF Power Level: 0 dBm nom. LO Power Level: +10 dBm nom. I & Q Output Characteristics Video Bandwidth, nom: DC to 100 MHz Output Impedance: 50 nom. Conversion Loss (RF to I or Q): 10 dB typ., 12 dB max. IF Balance (I to Q) Phase, @ Vc=+5V: 90 5 Bias Control: 0 to +15V Phase Tuning Range: 10 nom., @ fo Tuning Sensitivity: 4/V nom. Temperature Stability: 1 nom.,2 max. Amplitude: 0.2 dB max. Weight, nominal 0.55 oz (15.4 g) Operating Temp: -- 55 to +85C L - Package Outline NOTES: 1. Tolerance on 3 place decimals .010(.25) except as noted. 2. Dimensions in inches over millimeters. 3. Dimensions marked with * apply only at body. 4. All unmarked pins are case ground. LO Input Not Used Phase Adjust I Output RF Input Q Output 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-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. 24May96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 |
