- Optimized two radar RFICs for an X-band 8혻×혻8 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 8혻×혻8 phased-array receiver module is constructed using 16 2혻×혻2 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 2혻×혻2 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 0.37째 RMS phase error and a 2.17혻dB gain error over 360째 sweep.
