The low frequency tuners are a unique product technology using MPT 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.

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.

Focus Microwaves’ DELTA series of electro-mechanical tuners is designed specifically for high frequency on wafer measurements. The tuner’s low profile allows it to be placed within the wafer perimeter and allows for a direct connection between the probe tip and the tuner, eliminating all possible insertion loss between the DUT and the tuner. This revolutionary new tuner design enables the engineer to achieve optimum tuning range, with a tuner whose footprint and weight has been dramatically reduced.

Supports the latest 5G FR1 and IEEE 802.11ax standards up to 1GHz active load pull bandwidth capability Test the latest high bandwidth and high modulation cellular standards such as 1024QAM 802.11ax

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.
