The variable step attenuator presented here for measurement purposes, is an inestimable tool for accurate control of amplitude levels. In addition, it improves the impedance match between impedance-sensitive devices, such as amplifiers, oscillators and filters, lowering the VSWR of components connected in cascaded mode by providing isolation between the impedances.
Furthermore, the step attenuator is suitable for receiver front-end protection or as calibrated attenuator for receiving performance evaluation.
The attenuator in ladder configuration uses eight high quality low stray capacitance double pole double throw (DPDT) toggle switches to select different amounts of attenuation.
The unit provides 0-71 dB of attenuation in 1 dB step.
Based on Mini-circuits PAT+ series, wideband DC to 7GHz fixed ceramic attenuator cells of 1dB-2dB-3dB-5dB-10dB-10dB-20dB-20dB, it gives a precise reference of attenuation
BNC connectors protected with no short-circuited metallic dust caps are used at each end of the attenuator. Connector options available.
