eBook Overview

Mixers are a foundational element of RF and microwave communication systems. As wireless technologies continue to evolve toward higher data rates, wider bandwidths, and millimeter-wave operation, mixer performance increasingly influences overall system behavior.

This ebook introduces the fundamental principles of mixer operation and design, focusing on modern receiver and transmitter architectures used in 5G and emerging 6G systems.

This first installment in a two-part technical series establishes a common framework for understanding mixer behavior before addressing practical design and simulation techniques.

Topics covered include:

• The role of mixers in RF front-end architectures
• Frequency translation through upconversion and downconversion
• Core mixer topologies, including unbalanced, single-balanced, and double-balanced designs
• Diode-based and transistor-based mixer implementations
• CMOS, GaAs, and MMIC approaches for microwave and millimeter-wave systems
• Key performance metrics such as conversion gain, noise figure, linearity, isolation, and bandwidth
• Image frequency generation and suppression techniques
• Single-sideband (SSB), image-reject (IR), and I/Q mixer architectures
