GENERAL SPECIFICATIONS RF/LO Input Characteristics RF Bandwidth: 10% of fo Impedance: 50 nom. VSWR: 1.5:1 max. RF Power Level: 0 dBm nom. LO Power Level @ fo: +10 dBm nom. I & Q Output Characteristics Output Impedance: 50 nom. Conversion Loss (RF to I or Q): 10 dB typ., 12 dB max. IF Quadrature Balance (I to Q), @ 100 kHz IF Phase, @ LO=fo: 1 nom., 2 max. Phase, @ LO=fo5%: 3 nom., 5 max. Ampl., @ LO=fo: 0.2 dB max. Ampl., @ LO=fo5%: 0.5 dB max. Weight, nominal: 0.32 oz (9 g) Operating Temp: -- 55 to +85C Outline of E - Size Flatpack .160/4.06 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. NOTES: 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. Comprised of standard components, these units are optimized for high accuracy at a specified LO frequency and maintain specified performance across a bandwidth of 10% of the LO frequency. 3. I & Q networks can also be used in digital systems as a QPSK demodulator where it recovers two data channels from the incoming phase information. The QPSK input is applied to the RF port while the recovered carrier is applied to the LO port resulting in the two independent data outputs at the I and Q data ports. 4. Merrimac I & Q networks comply with the relevant sections of MIL-M-28837 and can be supplied screened for compliance with additional specifications for military and space applications requiring the highest reliability. 29Apr96 For further information contact MERRIMAC / 41 Fairfield Pl., W est Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 |
