DTF-4A-1250 1 - 3500 All specifications are as measured in a 50 system, at nominal LO power in a down converter application 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. Package Outline NOTES: GENERAL SPECIFICATIONS IF Frequency Range: Impedance: 1 - 1000 MHz 50 nom. Third Order Intermodulation Ratio Degradation: 3 dB typ. for IF VSWR of 3.0:1 Useful LO Drive Range: 3 dB of nominal SSB Noise Figure: Weight, nominal: Within 1 dB of Conversion Loss 0.15 oz (4.2 g) Operating Temperature: - 55 to +85C General Notes: 1. The DTF-A series Termination Insensitive Mixers cover the frequency range of 1 to 3500 MHz using transmission line hybrid junction techniques to isolate the diode rings from termination mismatch-induced reflections. This means the intermodulation ratio is independent of the IF port load impedance, so this unit is ideal for applications where a high performance mixer must drive a reactive load (e.g., filter) at the IF port. The DTF-A series and related models are available in PC, SMD and connectorized packages. 2. Merrimac offers a broad selection of Double Balanced Mixers ideal for a variety of signal processing functions with frequencies ranging from 20 kHz to 20 GHz and for applications from routine to very special. 3. Merrimac mixers comply with MIL-M-28837 and may be supplied screened for compliance with additional specifications for military and space specifications requiring the highest reliability. 29Apr96 Fo f t e i or i c t c M ERRI AC /41 Faifel Pl,W estCal r urh r nf maton on a t M ri d . dwel,NJ,07006 / 973-575l 1300 /FAX 973- 0531 575- |
