초록
In this study, we implement a spectrum extension system for frequencies over 100 GHz using a sub-harmonic mixer. A ×16 multiplier is customized to drive the local oscillator(LO) port of the sub-harmonic mixer from the first LO output frequency of a spectrum analyzer.The output power of the reference signal is measured precisely by using a power sensor, and the conversion loss corresponding to the output power of the spectrum analyzer is derived and tabulated. The performance of the spectrum extension system is evaluated by measuring the output power of the signal, which was over ?50 dBm in the frequency range of 112~130 GHz.
