The Model 751-004-070 from BroadWave Technologies is a 50 Ohm manual variable attenuator that covers DC to 2.5 GHz frequency range. The device provides 70 dB of attenuation in 10 dB steps. The attenuation accuracy is ±0.5 dB or 3 % (whichever is greater) and insertion loss is 0.6 dB maximum. Maximum VSWR is 1.50:1 and RF input power is 2-W average. The attenuator comes with SMA female RF connectors.
Manual variable attenuators designed by BroadWave provide an accurate method of varying the level of a signal from DC to 3 GHz. Standard connector options are BNC, N or SMA. Applications include test equipment, telecommunication systems, base stations, radar applications, high precision applications such as military and defense programs.
