Measurement of Voltage Level Output by Magnetic Tunneling Junction by Rectification of RF Signals (ADDENDUM)

摘要

In this experiment, the DC voltage output of a magnetic tunneling junction (MTJ) was measured. This was accomplished using both a broadband horn ridge antenna as a radio frequency (RF) source. Transmission frequencies ranged from 1 to 6 GHz at varied power levels of 0 to 20 dBm. The signal was received by a coplanar waveguide antenna. A MTJ rectified the RF signal to a DC voltage. Resonance was found at frequencies of 2.1 GHz and 5.6 GHz due to two different MTJ wafers used in manufacturing the detectors. At resonance, rectified voltages levels were approximately 0.3 mV.
