Passive Multipliers (FT)

High-Efficiency Frequency Multiplication Without External Bias

Farran’s FT Series passive multipliers are broadband frequency multipliers based on planar GaAs Schottky diode technology. These fixed-tuned, bias-free devices provide robust and efficient frequency multiplication across full waveguide bands — ideal for applications where simplicity, performance, and reliability are key.

With high conversion efficiency and compact waveguide design, Farran’s passive multipliers are well-suited for signal source development, LO chains, radar systems, and test and measurement environments. Each unit is engineered for plug-and-play integration into your millimeter-wave system.

What customers are saying

Testimonials and reviews from our customers
As a test engineer my role is to ensure that new designs, as well as established products, are measured with the utmost accuracy. Over the years, Farran’s FEV extenders have delivered unparalleled dynamic range and long-term stability of the measurements without the need for frequent calibrations. They can be easily configured with wide range of our VNAs and are seamlessly controlled via the VNAs user interface. Great customer support and direct access to Farran’s engineers, coupled with the FEV performance and their reliability, make my job simple and stress-free.
Principal Test Engineer European Radar & Sensor Testing Enterprise
As a manager of the R&D group, we needed to pivot to mm-wave frequency for our new development plan. Our existing test equipment required upgrading and after an extensive search, we found Farran’s FEV range of extenders to be the best solution for our needs. We had direct communications with all the relevant Farran personnel from the outset and were able to get real time feedback and support for the many questions we had prior to purchase. Overall, Farran’s FEV range is the perfect solution to our R&D mm-wave requirements.
