Silicon-based monolithic microwave integrated circuits (MMICs) present an interesting option for low-cost consumer wireless systems. SiGe/Si heterojunction bipolar transistors (HBTs) are a major driving force behind Si-based MMICs, because they offer excellent microwave performance without aggressive lateral scaling. This article reviews opportunities for receiver frontend components (low-noise amplifiers and mixers) using SiGe HBTs.
