Fixed Value Attenuators

Features:

• Values from 1 to 20 dB
• Dc - 1500 MHz
• Completely shielded
• Small size
• Rugged construction

Fixed value attenuators are useful for adjusting receiver system gain. For example, a fixed value attenuator may be used between the output of a preamplifier and the input to a receiver to lower the effective gain of the preamplifier without significantly affecting the noise figure of the system. The value of the attenuator reduces the system gain by a like amount. A 24 dB gain preamplifier followed by a 6 dB attenuator yields a system gain of 18 dB. Attenuators can also be used for measurement purposes, equalizing gains, system performance testing, etc. Power rating for the type BNC and type N attenuators is 1 watt. Type SMA is 0.5 watt. Maximum VSWR is 1.7:1.
