Abstract: Optimized two radar RFICs for an X‐band 8 × 8 phased‐array 4‐channel frequency‐modulated continuous‐wave receiver is proposed using 65‐nm CMOS technology and the beam steering operation of the receiver module is demonstrated. The 8 × 8 phased‐array receiver module is constructed using 16 2 × 2 phased‐array receivers and a 4‐channel receiver for implementation of monopulse radar. The array size is scalable with the proposed two chips solution. The 2 × 2 phased‐array receiver has novel vector‐sum phase‐shifter with 7‐bit resolution in low supply voltage. The measured result of the phase shifter shows 7‐bit phase states with a 0.37° RMS phase error and a 2.17 dB gain error over 360° sweep.
