Design Approaches for Established and Emerging RF Receiver Architectures

Traditionally, heterodyne architectures have been the preferred choice for radio frequency (RF) and millimeter-wave (mmWave) receiver architectures, excelling in noise performance, dynamic range, frequency coverage, selectivity, and reduction of EMI. However, recent advancements in high sample rate analog to digital converters (ADCs) and embedded signal processing have prompted a reassessment of both architectures.
