摘要：

A single resonance-type spin-torque microwave diode (STMD) can be used as a quadratic detector to determine the frequency f of an external microwave signal when the power P-rf of this signal is known. However, unless the signal's frequency f exactly coincides with the detector's resonance frequency f(res), there exists a finite frequency determination error Delta f. In this letter,we show theoretically and experimentally that if a pair of independent STMDs with different resonance frequencies connected in parallel is used for the signal frequency determination, knowledge of the signal power is not necessary, and the frequency determination error can be substantially reduced to Lambda f approximate to 30 MHz at the frequency of f approximate to 5.0 GHz.
