摘要：

In recent years, as communication speeds increase, the 300-GHz band has been attracting attention for its wide bandwidth. To realize transmitter in such a region, research has been conducted on up-conversion mixers operating at the 300-GHz band. The problem with conventional mixers is that they can't separate the LO and IF signal ports, and even if they could, harmonics would be generated near the RF band. In this work, we propose an up- conversion mixer with separate LO and IF ports and harmonic suppression. Using a 40-nm CMOS process, we realize the up-conversion mixer with a bandwidth of 19 GHz and a maximum output power of -42.69 dBm. If the LO signal of 5 dBm is input, the output power of approximately -20 dBm can be obtained.
