February 05, 2017 // By Jean-Pierre Joosting
The Model 651-030-006 is a single step voltage controlled programmable attenuator designed for use in scientific instruments.

The frequency range is DC to 1 GHz. Attenuation range is 0 to 6 dB in a 6 dB step with ± 0.4 dB attenuation accuracy. Insertion loss is 0.6 dB nominal while VSWR is 1.30:1 maximum. Input power is 1-W average with supply voltage of +15 Vdc at 30 mA nominal.

The RF connectors are SMA female and the control solder terminal features a feed-thru capacitor to prevent leakage
