Focus Microwaves - Cardiff Behavioral Model Software
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 Cardiff Model+ formulation has a number of unique benefits over alternative approaches where formulations are truncated. Once the formulation is extended, the model moves away from a local model, where multiple models are required to define an impedance space (i.e load lookup), to a model that has a set of coefficients that describes the behavior of a device over an entire impedance space. This dramatically reduces file size and also allows any interpolation to be defined by the model itself rather than relying upon the interpolation algorithm in the simulator. Also, as harmonic superposition is not assumed in the CM+ formulation, a full harmonic mixing model is uncovered describing harmonic interactions and improving model accuracy particularly for complex modes of operation.

The Cardiff Model portfolio is fully supported in all major EDS tools including Keysight Advanced Design System and AWR Microwave office. These models are ideal for release to customers. They are accurate and as they are black box no reverse engineering of the underlying technology is possible.

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).

Introducing Auriga’s 5th generation pulsed IV/RF characterization system delivers unparalleled performance, capturing measurements with incredible speed and accuracy. Pulsed IV (current-voltage) measurements have emerged as the preferred method of capturing current-voltage characteristics of active devices such as field effect (FETs) and bipolar junction (BJTs) transistors. With the growing popularity of higher-power devices, like GaN HEMTs, LDMOS, SiC, and graphene, current and voltage requirements are constantly being pushed higher and higher.
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’ 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.
