Abstract :
A miniature battery-operated microwave power monitor is described which operates across the threshold range of biologically dangerous power levels with approximately frequency-independent characteristics up to about 100GHz. CMOS circuitry causes an alarm signal to occur, or enables one to integrate the total microwave energy received over a given period on the basis of a thermal change of resistance in a thin Ge film due to microwave absorption.
