Abstract

Shock wave generation can be triggered by a microwave frequency when a GaAs sample is pulsed or biased at a threshold voltage level. The generation of these shock waves produces a time dependent negative resistance causative of oscillations at the output terminals dependent on circuit loading.

Microwave Detector Circuit

Shock wave generation can be triggered by a microwave frequency when a GaAs sample is pulsed or biased at a threshold voltage level. The generation of these shock waves produces a time dependent negative resistance causative of oscillations at the output terminals dependent on circuit loading.

An operation of this circuitry provides a microwave detector utilizing detection above a threshold level. By pulse modulating the circuit at terminal 10 with radio frequency applied to input terminals 12 and 14, the envelope information is obtained as output from terminals 16 and 18. Detection gains of approximately ten times are obtained.

Additionally, the period of the oscillations at terminals 16 and 18 is a function of the microwave power level. The effect is useful for controlling microwave power levels.
