Focus Microwaves' Harmonic Tuners are engineered to enable precise control of impedance at the fundamental and harmonic frequencies (typically f₀, 2f₀, and 3f₀), making them essential for nonlinear device characterization and power amplifier design.
These tuners feature multiple cascaded probes within a single tuner body, allowing independent or simultaneous tuning at multiple frequencies. Their robust design ensures high tuning accuracy, minimal insertion loss, and excellent repeatability across a broad frequency range. Harmonic tuners are the ideal solution for advanced Load Pull measurements where harmonic control is critical.

The Low Frequency Tuner (LFT) is a unique product technology using M algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors. The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.

Focus Microwaves
Focus Microwaves is a pioneering engineering company, built around the innovations of its founder Dr. Christos Tsironis who developed his first manual tuner in 1973 and is the inventor of most existing electro-mechanical tuner families. The success of Focus is based on the engineering and manufacturing skills of its highly motivated and experienced team of engineers and technicians, who have been trained and encouraged to develop new technologies. In addition, listening to our customers needs and insights helps us discover and develop new and measurement methods on an ongoing basis, relentlessly pushing the limits of what is possible.
From humble beginnings in 1988, Focus has become the main supplier of advanced Load Pull and Noise Tuner Systems. Our mission is to provide effective, reliable and innovative solutions for non-50 Ohm testing (Noise and Load Pull) of RF microwave transistors, thus enabling our customers to compete in the marketplace with better designs and to advance the understanding and knowledge of the field.
