A 220 GHz Orthogonal Modulator Based on Subharmonic Mixers Using Anti-Paralleled Schottky Diodes
文献摘要：
In this paper,A 220 GHz orthogonal modulator based on two symmetrical subharmonic mix-ers is designed,analyzed and measured,where the mixers are implemented basde on antiparallel Schottky diodes.The orthogonal modulator consists of a 90° phase shifted 220 GHz 3 dB coupler,two sub-harmonically pumped mixers and an in-phase 110 GHz 3 dB power divider.The IF output signals are in-phase(Ⅰ)branch and quadrature(Q)branch operating from DC±3.5GHz.In the back to back experimentaltests,it is shown that the conversion loss of the two 220 GHz I/Q mixers is less than 30 dB when the IF operating frequency is DC—3.5 GHz,IF in-put power is—10 dBm and the LO power is around 6 f mW.Based on floating-point simulation,the amplitude]and phase imbalance of the I/Q mixer are less than 0.2 dB and 2 degree respectively.When the 220 GHz modu-lator and demodulator are set in a back to back configur-ation,a signal-to-noise ratio of 21 dB can be obtained us-ing the 16QAM modulation type.
