Ku-Band GaAs Microwave Monolithic Integrated Circuits

The design, fabrication and measured result of Ku-band GaAs monolithic IC are described in this paper. The matching networks of this circuit have been designed with the method of combining computer analyzing and circuit modeling to FET. A two-sta-ge monolithic circuit has been successfully fabricated into a chip with dimensions of 1.9×3.2×0.1mm. This type of MMIC operates in the range of frequency 14.5～15.4GHz, with output power P_0≥100mW, gain G_p≥5dB and the gain flatness in the same frequency band △G_p≤±0.75dB.
