IEEE Transactions on Microwave Theory and Techniques
Special Issue on
Power Amplifiers for Communications and Satellite Applications

Submission Deadline: December 31st, 2025

Motivation: The design and implementation of power amplifiers (PAs) remain a cornerstone of RF and microwave transmitters, enabling energy efficient transmission of signals across wireless and satellite communication systems. The demand for high-performance, energy-efficient, and broadband PAs continues to grow with the evolution of 5G/6G cellular networks, satellite constellations, non-terrestrial networks, and emerging frequency bands up to millimeter-wave.

In 2026, the RF/microwave community will celebrate the 90th anniversary of the Doherty Power Amplifier and the 10th anniversary of the Load Modulated Balanced Amplifier (LMBA). These milestones mark a crucial moment to assess recent developments and future directions in high-efficiency amplification. This Special Issue aims to feature cutting-edge research on advanced PA architectures, enabling technologies, and system-level innovations for high-efficiency, linear, and broadband power amplification in both terrestrial and spaceborne communication systems.

Scope: We invite original research contributions and high-quality review articles covering, but not limited to, the following topics:

  • High-efficiency power amplifier architectures (e.g. Class F/G/J/E, Doherty, Chireix, LMBA, Outphasing)
  • Digital PA architectures
  • Multi-way and broadband load modulation techniques
  • GaN/GaAs/InP-based PA design and MMIC implementations
  • PA linearization techniques and digital predistortion
  • Thermal-aware and electro-thermal co-design of power amplifiers
  • Adaptive biasing and supply modulation techniques (e.g., ET, EER)
  • PA characterization under modulated signals and extreme conditions
  • Power combining strategies for mm-wave and sub-THz frequencies
