Abstract :
The performance of a single channel microwave attenuation measurement system is compared to a dual channel implementation. The results show that a single channel system is more suitable for attenuation measurement from 10 MHz to 4 GHz since it can cover this frequency range using only two bands, while a dual channel system has to be used for attenuation measurement from 4 GHz to 26.5 GHz since the receiver reading is more stable in this frequency range.
