Focus Microwaves - Sub-18GHz Tuners
Focus provides the deepest portfolio of wideband fundamental and harmonic passive tuners. Passive impedance tuners generate controllable reflection factor (Impedance) across the smith chart over a given frequency range. Focus uses two basic technologies:
-
From 100MHz to 120GHz we use the slide screw technique in which a reflective probe is inserted into a low loss slotted transmission line.
-
For frequencies from 10MHz to 170MHz we use a lumped element technology, whereby variable capacitors are connected with optimized lengths of coaxial cable. To view our Low Frequency Tuners, Click Here!
Most Focus Passive Tuners use long lasting RF probes which are designed for optimal tuning accuracy and are free of spurious resonances. The combination of multiple probes provide ultra wideband coverage in one single tuner. All Focus Passive Tuners are LAN controlled and include on-board impedance synthesis firmware.

The Focus Compact Model (FCM) utility is a streamlined software package designed to be used with Focus’ AURIGA high-end Pulsed-IV system, that is used to generate Compact Models for transistors from their Pulsed-IV and wideband pulsed s-parameter data.
This is achieved by generating a network of lumped circuit elements that represent accurately the fundamental linear & non-linear behavior of the device over a broad range of bias and power range.
The result of the modeling is a netlist and compatible with- the most common CAD tools used in RF Design; such as AWR Microwave office (MWO) and Keysight PathWave Advanced Design System (ADS).
Focus’ modular microstrip, high power and ultra low loss coaxial RF Test Fixtures are designed mainly for load pull testing of packaged transistors. All Focus test fixtures come with TRL calibration standards and support most transistor packages sized from less than 0.1″ and up to 1″.
Introducing Auriga’s 5th generation pulsed IV/RF characterization system delivers unparalleled performance, capturing measurements with incredible speed and accuracy. Pulsed IV (current-voltage) measurements have emerged as the preferred method of capturing current-voltage characteristics of active devices such as field effect (FETs) and bipolar junction (BJTs) transistors. With the growing popularity of higher-power devices, like GaN HEMTs, LDMOS, SiC, and graphene, current and voltage requirements are constantly being pushed higher and higher.

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.
