The model 651-038-020 step attenuator covers DC to 2.5 GHz.
BroadWave Technologies has introduced the 651-038-020 voltage-controlled programmable attenuator designed for use in scientific instruments. It features an attenuation range of 0 dB to 20 dB in 20 dB steps with ±0.6 dB attenuation accuracy. It’s frequency range is DC-2.5 GHz. Insertion loss is 0.6 dB maximum while VSWR is 1.40:1 maximum. It’s input power is 1 W average with a +15 VDC supply voltage at 30 mA nominal. It uses SMA RF receptacles for its connectors. Its control solder terminal features a feed-thru capacitor to prevent leakage. The attenuator is available in other frequency ranges and attenuation steps.
