基于肖特基二极管的宽带低本振功率太赫兹四次谐波混频器
A wideband terahertz planar Schottky diode fourth-harmonic mixer with low LO power requirement
摘要
Abstract
A wideband terahertz fourth-harmonic mixer with low local oscillator(LO)power requirement basedon anti-parallel planar Schottky diodes is proposed. In order to realize best performances of the mixer,the rela-tions between the parasitic elements of Schottky diodes and the mixer's performances are analyzed. The main pa-rameters of Schottky diodes are optimized to reduce the optimum LO power of the fourth-harmonic mixer. Mea-sured results show that the conversion loss of the proposed mixer based on specialized diodes is 14. 2～20 dB with-in a wide band from 340 to 490 GHz with optimal LO power of 7 mW,while the noise temperature is 4020～17100 K in this frequency range.关键词
