In this report, we describe the complex impedance of spin torque nano oscillator (STNO) devices. We determined that the STNO is a nonreactive, real-resistance device with single-valued resistance in the broadband frequency range of 500 MHz to 10 GHz (the limit of our test conditions), and that STNOs do not require an external circuit or conjugate matching to operate in a transmitter configuration. We report the first demonstration of the ...
