Abstract
This letter presents a bolometric power sensor for transfer power standards in a waveguide. This is a novel design of the microwave power sensor with an integrated filter function. An analytical power sensor synthesis technique using the coupling matrix is presented here for the first time. An ${X}$ -band power sensor with the integrated third-order Chebyshev filter function was designed and manufactured. The filtering sensor uses a small bead thermistor as a sensing element. Measurements are in good agreement with simulation and theoretical expectations.
