Abstract
A new magnetoresistive sensor for measurement of transmitted pulse power in an unmatched waveguide transmission line has been developed. The sensor has a linear dependence of output signal in a dynamic range of 40 dB at 42 kW maximum pulse power and average power level of 50 W. The output signal of the sensor is proportional to the instantaneous value of the input active power level. It displays an input pulse form in the 0.2-500 ¿s time band and has the equivalent directionality up to 30 dB for a bandwidth of 2% and up to 20 dB for a bandwidth of 8% respectively.
