[Abstract]:This paper reports a GaN T / R MMIC. used in Ku band. The chip is fabricated by 0.15 渭 m GaN HEMT device process and integrates the receiving and transmitting channels of the T / R module. The chip area is 7.00mm 脳 3.32mmm. The developed MMIC integrates 5 bit digital attenuator, 5 bit digital phase shifter, front stage low noise amplifier, rear stage low noise amplifier, drive amplifier, power amplifier, public branch small signal switch and transceiver switching power switch. It is found that the gain of receiving channel is more than 21dB, the noise coefficient is less than 3.5dB, the gain of transmission channel is more than 20.8 dB, the saturation power is more than 40.8dBmand the typical additional efficiency is 30. The 5-bit digital phase shifter and 5-bit digital attenuator have normal function and meet the design requirements.
