Focus Microwaves - Manual Tuners
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).

Non-linear measurement data is often used to create a behavioral model for high frequency components. Formulations of these models have been defined in terms of traveling waves, with a desire to represent nonlinear behavior of high frequency transistors through a direct extension from linear s-parameters.
The Mesuro model portfolio is comprised of two variations of a behavioral model – each targeted at a particular end use – Cardiff Model Lite (CML), where the desired output is a local model, and Cardiff Model+ (CM+), which incorporates higher order mixing terms allowing a single model to fit over a range of impedance space.
The LN112-30 Lens Adaptor is used for creating a 30° focused beam spread when attached to a SL112 or SL162.

Focus recommends TRL Calibration Kits for applications such as load pull & noise parameters. Due to high reflection and low loss, tuner S-parameter measurements represent a challenge for VNA’s, because of error term determination and coupler directivity. Long experience has taught us not to rely on other calibration techniques than TRL (Thru-Reflect-Line). The popular SOLT technique is conditionally useable, but not guaranteed, up to 4GHz. The much convenient ECal method has provided questionable and inconsistent results. Our Customers are advised to be very careful with VNA calibrations, because the whole measured data depends on that.
Because of this, and to save our customers time and doubt, Focus has developed and offers a set of precise and reliable TRL calibration kits from 0.03 to 110 GHz with the following connector types: 7/16, N, APC-7, 3.5mm, 2.9mm, 2.4mm, 1.85mm, WR-15, WR-10. Our calibration kits are compatible with all commercial network analyzers.

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’ modular microstrip, high power and ultra low loss coaxial RF Test Fixtures are designed mainly for load pull testing of packaged transistors. All Focus test fixtures come with TRL calibration standards and support most transistor packages sized from less than 0.1″ and up to 1″.
