A 210-230GHz SiGe Hybrid Mixing System with Pre-And Post-Driving Amplifiers
The article presents a 220GHz terahertz (THz) mixer based on a 130nm SiGe process. This mixer utilizes a Gilbert double-balanced mixer topology and employs a cross-coupled structure with asymmetric capacitive compensation to optimize the layout, enhancing LO-RF isolation. The local oscillator (LO) and radio frequency (RF) ports of the mixer are connected to a driver amplifier and an output power amplifier, respectively, achieving an operational frequency range of 210-230GHz, a conversion gain of 13dB, and a maximum output power of 5.7dBm.
