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.

Discover Focus Microwaves' wideband fundamental tuners. The C-Series (Computer-Controlled Microwave Tuners) feature one to three wideband probes, enabling exceptionally broad frequency coverage—ideal for high-power and wideband noise applications.
Designed for precision, the tuner's long-lasting RF probes ensure optimal tuning accuracy while eliminating spurious resonances. The integration of multiple probes within a single tuner provides ultra-wideband coverage, making it a versatile solution for demanding RF applications.
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.
Auriga’s Bias Tees balance impressive RF performance with heavy-duty power handling across multiple frequency bands ranging from 0.1 GHz to 67 GHz. They are designed for rigorous usage without sacrificing RF performance.
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.
Discover Focus Microwaves' versatile MMT series of manual tuners, offering octave and multi-octave bands from 400MHz to 18GHz. With the same RF technology and precision as our automatic tuners, they ensure high VSWR at the DUT reference plane for reliable performance. Enhance harmonic tuning with options -H2 and -H23, inspired by our harmonic rejection tuners (PHT). Experience precision in manual tuning with Focus Microwaves.
Focus Microwaves introduces a cutting-edge noise measurement system comprising three integral components: the Input Noise Module (INM), Output Noise Module (ONM), and Noise Module Controller (NMC). This system extracts precise noise parameters, offering rapid, stable measurements and optimized performance with dedicated software for calibration and analysis.
Discover precision phase reference solutions from Focus Microwaves, spanning frequencies from 100 MHz to 8 GHz, 30 GHz, and up to 67 GHz. Our phase reference units are indispensable for achieving precise phase calibration in RF and microwave measurements across a wide range of frequency bands.
The Focus Phase Stable Cable is an advanced RF cable designed for superior performance and reliability in demanding applications. Engineered with meticulous attention to detail, this cable features high-quality materials and precise manufacturing standards to ensure exceptional phase and amplitude stability, low insertion loss, and robust environmental resistance. Suitable for a wide frequency range from DC to 110GHz, it is ideal for applications requiring stable electrical performance under dynamic conditions.
