What is a step attenuator?April 25, 2024 - 11:44 am
A step attenuator is a variable attenuator that can have its attenuation setting varied over an attenuation range by a specific dB step size. All attenuation settings are referenced to the insertion loss. This means that the minimum setting (0dB) is the insertion loss state of the step attenuator. For example programmable attenuator model 50P-1857 […]
What is the use of a fixed attenuator?April 15, 2024 - 11:36 am
A fixed attenuator has two main uses: decrease signal power level, improve poor VSWR. A fixed attenuator is a passive device with internal resistors whose resistive values are calculated base on the impedance (50 Ohm or 75 Ohm) and the desired attenuation value. The attenuation value is expressed in terms of decibel (dB). When the […]
What is the difference between reactive and resistive power dividers?April 12, 2024 - 2:42 pm
Understanding the difference between reactive and resistive power dividers will help you create the best functionality for your RF testing setup. Their functionality is similar but yet different. Resistive Power Dividers Their construction is a star configuration. All ports are symmetrical. There is no common port with resistive type design. The star configurations functions as […]
