Insertion Loss: 0.5 dB max. VSWR: 1.5:1 max. Impedance: 50 Ω nom. Average Power: 2 Watts max. Operating Temperature: -- 55° to +85°C Typical Performance Attenuation in dB Insertion Loss in dB General Notes: NOTES: 1. The AUM/AUMP-15A series has been designed for wideband ECM systems and other microwave applications in the 1 to 8 GHz frequency band where precise attenuation must be maintained over a wide variety of military and laboratory environments. 2. The AUM/AUMP-15A series of attenuators use ferrite absorption of microwave energy for long term stability and high reliability. Applications include signal and LO power control, automatic level control and impedance matching. 3. These units can be supplied screened to meet specific military and commercial high reliability applications. 1. Tolerance on 3 place decimals ±.020(.51) except as noted. 2. Dimensions in inches over millimeters. 3. Counterclockwise shaft rotation increases attenuation. 04Mar96 For further information contact MERRIMAC / 41 Fairfield Pl., West Caldwell, NJ, 07006 / 973-575-1300 / FAX 973-575-0531 AUM 15A & AUMP- MICROWAVE ATTENUATORS 1 to 8 GHz / 0 to 20 dB / Ferrite / Excellent Temperature Stability / MIL-E-5400 Class 3 / SMA AUMP-15A NOTES: 1.
