ABSTRACT:
A radiation detector for free space microwave radiation uses thin film resistive strips, having an equivalent surface resistivity that is large compared to the characteristic impedance of free space, and diode circuits in series with the strips for deriving signals monitoring the radiation intensity over a broad frequency range. The diode circuits are constructed to operate with a uniform response over that frequency range.
