Focus Microwaves - Waveguide Tuners
Focus Microwaves pushes the boundaries of tuner technology once again. While 6G frequencies and applications are still being defined, Focus took the initiative and developed a new family of waveguide tuners designed for frequencies greater than 110GHz. Leveraging the success and technology of the DELTA tuners (industry standard for direct connect on wafer applications) and combined it with the micro-metric accuracy and repeatability of the small footprint omega tuners. These new waveguide tuners will revolutionize the Sub-THz bands.
Starting with models from 26 to 40 GHz and now up to 330 GHz using standard WR-3, WR-5, WR-6, WR-10, WR-12, WR-15, WR-22 and WR-28 waveguide sections. The extreme high horizontal (2.5μm) and vertical (1.5μm) probe movement resolution allows dense impedance coverage up to the highest frequency. Focus’ series of waveguide tuners provide high tuning range in a small footprint, making them ideal for on-wafer applications. Multiple models are available for Ka, V, E, W and D bands.
The extreme low loss RF probes used in the waveguide tuners are also designed for optimal tuning accuracy and repeatability and are free of spurious resonances. All Focus tuners are LAN controlled and include on-board impedance synthesis firmware (iTuner) based on previous calibration.

More Product Information
Focus offers a complete range of manual tuners. The MMT series use the same RF technology and precision as a comparable automatic tuner.
They are available in octave and multi-octave bands between 400 MHz and 18 GHz and provide high VSWR at DUT reference plane with a high reliability.
For harmonic tuning requirements, the MMT series can be enhanced, referring to as option –H2 and –H23, using a similar concept as Focus’ harmonic rejection tuners (PHT).

Bias tees with a perfect balance of RF performance and DC power handling
Auriga’s Bias Tees balance impressive RF performance with heavy-duty power handling across multiple frequency bands ranging from 100 MHz to 67 GHz. They are designed for rigorous usage without sacrificing RF performance. Only the highest-quality materials are used to minimize signal loss and enable efficient heat removal.
An impedance tuner is an apparatus, which generates controllable reflection factor (Impedance) over a certain frequency range. Focus uses two basic technologies:
a) For frequencies from 100MHz to 110GHz (and above) we use the slide screw technique (models Multi Harmonic MPT, wideband (fundamental) CCMT, harmonic rejection PHT), in which a reflective probe (slug) is inserted into the slot of a low loss slotted transmission line (slabline or waveguide).
b) For frequencies from below 10MHz to 170MHz we use a lumped element technology (models LFT), whereby variable capacitors are connected with optimized lengths of coaxial cable.
