To meet the ever-growing demand for higher data rates in communication networks and higher range and velocity resolutions in automotive radar sensors, fifth-generation (5G) new radio (NR) transceivers and radars used in autonomous vehicles use spectrally efficient modulation formats with large channel bandwidths available at millimeter wave (mm-wave) frequencies. However, designing energy-efficient broad-band transceivers with low manufacturing cost at mm-wave frequencies is extremely challenging because of the performance degradation of integrated circuit (IC) components, impairments due to packaging, and increased free-space path loss. This thesis presents a high-performance, compact, low-cost mm-wave transceiver solution for 5G NR and automotive radar sensors. A 28-GHz transceiver based on the local-oscillator (LO) phase-shifting architecture enabling gain-invariant phase tuning is designed in a 65-nm CMOS technology with wirebond-based packaging, enabling low manufacturing cost.
