The 33320H is a DC to 18GHz programmable step attenuator. It offers exceptional repeatability and reliability. Attenuation in 1dB steps from 0 to 11dB. Precision gold-plated leaf springs ensure long-life (over 5 million cycles) and very high attenuator repeatability (typically 0.01dB). A maximum switching time of 20ms (including contact settling) speeds automatic testing. Custom step attenuator/switch combinations are possible. The 11713A Attenuator/Switch Driver can be used to provide control for up to two step attenuators and two RF switches.
