ABSTRACT:
A microwave or other r.f. radiation detector in which a tunnel diode or other negative resistance device exhibiting the proper I-V (current-voltage) characteristics is biased in the positive resistance region near the voltage point at which the peak current occurs. Microwave or any other r.f. signal is picked up and detected by the tunnel diode such that an oscillation circuit connected thereto is caused to oscillate. The frequency of oscillation varies in accordance with the amplitude of the detected r.f. and is monitored with an earphone and/or a meter.
