Abstract:An S-band image rejection receiver monolithic microwave integrated circuit (MMIC) was developed based on the RC-CR poly-phase network technology,with an S-band low noise amplifier (LNA),a differential IQ frequency mixer,a local oscillator (LO)-drived amplifier,an RC-CR polyphase network filter and other circuit units integrated on the MMIC chip.The S-band image rejection receiver on a chip was realized and the size miniaturization problem of the image rejection receiver was solved.The results of the circuit and electromagnetic field software simulation and the fabrication with the GaAs pseudomorphic high electron mobility transistor (PHEMT) process show that the noise figure is less than 1.8 dB in the S band,the gain is larger than 12 dB,and the image rejection is larger than 35 dBc in the intermediate frequency bandwidth of (150±5) MHz.The chip size of the MMIC is 4.8 mm×2.5 mm×0.07 mm.The image rejection receiver MMIC features excellent specifications,small size and high integration,and can be widely applied in various phased array radars and communication systems that require size miniaturization.
Keywords:monolithic microwave integrated circuit (MMIC)  GaAs pseudomorphic high electron mobility transistor (PHEMT)  image rejection  poly-phase network  differential IQ frequency mixer
