Microwave signal detection by a system of two independent spin-torque microwave detectors

Abstract

It is well known that a spin-torque microwave detector (STMD) can be used for the determination of a frequency of an external microwave signal. We show that application of two independent STMDs connected in parallel at microwaves can substantially decrease the frequency determination error. We believe that obtained results are important for the practical development and performance optimization of microwave frequency detectors and other microwave devices based on STMD arrays.
