Explore the capabilities of our 120GHz Harmonic Load Pull system, leveraging Focus Microwaves' advanced DELTA series tuners. Optimize RF and microwave device performance through precise harmonic measurements and impedance tuning, crucial for applications in 5G, satellite communications, and beyond.
The Low Frequency Tuner (LFT) is a unique product technology using M algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors. The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.
Discover Focus Microwaves' versatile MMT series of manual tuners, offering octave and multi-octave bands from 400MHz to 18GHz. With the same RF technology and precision as our automatic tuners, they ensure high VSWR at the DUT reference plane for reliable performance. Enhance harmonic tuning with options -H2 and -H23, inspired by our harmonic rejection tuners (PHT). Experience precision in manual tuning with Focus Microwaves.

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.

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.
