초록

The Ku-band GaAs MESFET mixer is designed and implemented using the LINMIC+, the microwave CAD simulator. The RF and IF is 14.0GHz and 1.0GHz, respectively. P$_{LO}$ is 0dBm, it can be obtained 5.8dB of the minimum noise figure at 1.4GHz and 5.8dB of the maximum conversion gain at 1.45GHz. Effects of bias and power level of local oscillator frequency are observed and the characteristics are verified.
