The 5G-New-Radio (NR) standard in millimeter wave (mm-wave) bands requires a low-cost antenna module consisting of a phased-array transceiver with beamforming [1], an antenna array, and a power management IC (PMIC). Since a typical on-chip mm-wave CM

In the recent 3GPP standard, 5G New Radio (NR) in the sub-6GHz frequency band supports up to 100MHz bandwidth (BW) for uplink channel and requires fast on/off transition below $10 \mu \mathrm {s}$ to support short transition-time interval (TTI). Thus

Uplink carrier aggregation (UL-CA) and high-power user equipment (HPUE) are proposed in the recent 3GPP standard [1]. UL-CA increases data-rate by aggregating intra-or inter-band carriers, and requires a supply modulator (SM) IC to generate two indep
