What is the use of a fixed attenuator?
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 […]
