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

About Focus Microwaves

Focus Microwaves Inc. is an Engineering and Manufacturing Corporation in Montreal, Canada, specializing in automatic measurement systems, based on precise electro-mechanical impedance tuner products, accessories, test software and associated applications.


Since 1988, Focus Microwaves innovates, manufactures, installs and supports automatic noise and load pull measurement systems, using our high precision impedance tuners from 10MHz to 140GHz. Our load pull, harmonic load pull and noise measurement systems enable our customers to gain a competitive edge in:

  • Designing power and low noise amplifiers

  • Improving mobile phone performance

  • Optimizing transistor technology

  • Validating transistor large signal models

Focus Microwaves became a leader in the industry by promptly responding to customers’ needs and pioneering most microwave tuners and applications. 

We design, manufacture and support all our products, especially automatic impedance tuners from 10MHz to 110GHz and on-wafer integrated Load Pull and Noise measurement systems.


We hold most relevant patents related to electromechanical impedance tuners. Since 1989 our products helped designers of power and low-noise amplifiers to shorten their design cycles and gain a competitive edge.

Our customers’ demands helped us create most products and applications in this field. The result to date is olver 1000 Focus systems using more than 2500 automatic wideband and harmonic tuners.

We offer standard and customized solutions for R&D and production testing as stand-alone hardware and fully-integrated systems. 

  • Wideband Noise parameter measurement and extraction

  • Nonlinear active and passive Load Pull (CW and Pulsed)

  • Harmonic and Time Domain Load Pull 

  • On-wafer turn-key solutions including vibration-free probe stations and pre-matching bend-lines

  • DC, Pulsed IV, S-parameter measurements using 3T and TRL calibrations
