摘要：
A 28GHz, small footprint phased-array front end module leveraging high integration capability of CMOS process and 17dBm output power with 18% efficiency of GaAs PA + SOI switch (SW) is presented. The maximum EIRP of the hybrid module for QPSK signal is 27.5dBm using 2 chains. The hybrid module dissipates 1009mW for DFT-s-OFDM QPSK uplink signal at 27dBm EIRP, saving 18.5% of a CMOS mmWave module's Pm. A mobile terminal with the 2-way hybrid modules shows 22.9dBm EIRP at 50%-tile CDF which is 0.8dB higher than the spherical coverage with the conventional 4-way modules.
