title = "A 28-nm CMOS D-Band Passive Modulator Achieving 43-dB Image Rejection Ratio",
abstract = "This paper presents a D-band sub-harmonic IQ modulator in 28-nm CMOS, achieving a 43 dB image rejection ratio (IRR) with zero DC power consumption. The design integrates a Lange coupler and stacked metal passive components to reduce insertion loss and enhance quadrature accuracy. The modulator achieves a conversion gain (CG) of -8 dB and an average IRR of 40 dB from 142 GHz to 152 GHz. Measurement results confirm that the proposed architecture effectively mitigates phase and amplitude mismatches, making it a promising candidate for high-frequency communication systems.",
