The Focus Microwaves Group comprises Focus Microwaves Inc., Mesuro Ltd. and Auriga PIV Tech Inc. They are All Engineering and Manufacturing Corporations based in Montreal (Canada), Cardiff (UK) and Merrimack (USA) respectively.

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 products 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.

Mesuro’s technology has been developed as a result of over a decades’ research at Cardiff University’s renowned Institute of High Frequency and Communication Engineering.

The Institute was founded by Professor Paul Tasker in 1997 and has grown rapidly to establish an international reputation in the fields of non-linear measurement systems, device characterization, and circuit design. The Institute works with many of the leading companies in the RF communications field to address significant technical challenges through fundamental research.

In January 2015, Focus Microwaves acquired Mesuro Ltd, taking sole ownership of the shares, IP, load pull and modelling technologies of the organization.

Auriga PIV Tech. Inc. develops and provides pulsed IV/RF characterization systems and bias tees. It offers its products for current–voltage measurements. Auriga PIV Tech. Inc. was formerly known as Auriga Microwave, Inc. The company was founded in 2004 and is based in Merrimack, New Hampshire. Auriga PIV Tech. Inc. operates as a subsidiary of Focus Microwaves Inc.

In February 2015, Focus Microwaves acquired the Pulsed IV and Bias-Tee lines of AURIGA. Out of a main concern regarding support of existing Auriga customers and in view of the potential of these valuable product lines, which fit seamlessly into Focus’ own modular pulsed IV, RF accessory and nonlinear modelling technology of MESURO, which Focus acquired last January, Focus also hired key Auriga personnel, in order to support customers, fulfill existing and pending pulse system orders and to push further product development.

Focus operates the Auriga PIV and BT lines out of its new location in Nashua, N.H. For further information please contact your local Auriga representative
