Focus Microwaves – Solutions by ATV Systems
As the European distribution and application partner for Focus Microwaves, ATV Systems GmbH delivers fully integrated measurement solutions for the nonlinear characterization of RF, mmWave and sub-THz devices. We combine the world-leading load-pull and noise tuner technology of Focus Microwaves with the wafer probe systems and RF probes of our parent company MPI Corporation, together with our own integration and automation expertise. The result: turnkey load-pull systems precisely tailored to the demands of power amplifier and transistor development. With the acquisition of Focus Microwaves by MPI Corporation and its integration into the Advanced Semiconductor Test (AST) Division, probe stations, TITAN™ RF probes and impedance tuners now come from a single corporate group – a decisive advantage when configuring precise on-wafer load-pull systems.
Why Choose ATV Systems as Your Load-Pull Partner?
Building a load-pull measurement setup is a complex undertaking. Impedance tuners, probe station, RF probes, vector network analyzer, signal sources, cables, bias tees and software must all be carefully matched, integrated and calibrated as a complete system. For on-wafer measurements in the mmWave range, the loss between probe and tuner alone can determine the quality of every single measurement.
ATV Systems eliminates this complexity as your single point of contact. With over 20 years of experience in semiconductor test and measurement, we operate at the interface between Focus Microwaves tuners and MPI wafer probe systems. We configure, integrate, validate and support your measurement setup – minimizing time to first reliable load-pull measurement and ensuring reproducible results across your sites.
Application Areas
Fundamental Load Pull (Entry Level & Broadband)
For classic power amplifier characterization and getting started with load-pull measurements, we offer the CCMT series (Coaxial Computer-Controlled Mechanical Tuner). With a single probe and fundamental-only tuning (f0), these tuners are broadband, easy to calibrate and cover frequency ranges from 0.8 GHz to 65 GHz.
Typical applications:Pout, gain and PAE optimization, classic mobile communication bands, first-time load-pull setups without harmonic requirements, component validation
Harmonic Load Pull (Multi-Purpose Tuners)
The MPT series (Multi-Purpose Tuner) is the core competency of Focus Microwaves. Multiple independently positionable probes enable simultaneous tuning of the fundamental and harmonics (f0, 2f0 and partly 3f0). This makes amplifier classes such as Class-F, Class-F⁻¹ and Doherty possible – with significant efficiency gains compared to fundamental-only tuning.
Typical applications: GaN power amplifiers, 5G mmWave, Class-F/Doherty design, wafer and package test, harmonic waveform engineering
On-Wafer mmWave Load Pull (DELTA Low-Profile Tuners)
For on-wafer measurements in the 5G and mmWave range, the DELTA series offers the lowest-profile design on the market. Mounted directly behind the RF probe, it minimizes the loss between probe and tuner and thereby achieves a higher effective |Γ| at the wafer reference plane. The DELTA tuners were developed specifically for integration with MPI probe stations – a direct benefit of our shared group affiliation.
Typical applications: On-wafer load pull into the mmWave range, 5G FR2 characterization, 120 GHz harmonic load pull, low-loss wafer-level measurements
Sub-THz Load Pull (Waveguide Tuners)
Above approximately 50 GHz, coaxial losses become too high – here, waveguide tuners are the method of choice. Focus covers all standard bands from Q through V, W, D, G to Y, reaching frequencies up to 330 GHz in combination with VNA frequency extenders.
Typical applications: 6G and SatCom development, radar and imaging applications, radio astronomy, research at universities and national research centers
Active- and Modulated Load Pull (Mesuro)
With the Mesuro platform acquired by Focus Microwaves, we offer active load-pull systems for the most demanding tasks in amplifier development. The MB series enables waveform engineering directly at the DUT reference plane and supports modulated signals (5G NR) as well as the X-parameter methodology.
Typical applications: Advanced PA R&D, Class-J/Chireix design, waveform reconstruction, characterization with modulated signals, 5G/6G research
Pulsed-IV and Noise Characterization
With the Mesuro platform acquired by Focus Microwaves, we offer active load-pull systems for the most demanding tasks in amplifier development. The MB series enables waveform engineering directly at the DUT reference plane and supports modulated signals (5G NR) as well as the X-parameter methodology.
Typical applications: Pulsed-IV measurements, GaN trapping effects, noise parameter extraction, isothermal and isodynamic device characterization
Our Services
Consulting and System Configuration
Our application engineers analyze your measurement requirements and qualify the right tuner technology – from the passive CCMT or MPT series through DELTA on-wafer tuners to active Mesuro systems – and configure a measurement setup that precisely fits your application.
Integration and Validation
We integrate the tuner, probe station, RF probes, VNA and software into a calibrated complete system and validate performance against agreed acceptance criteria. Every system is thoroughly tested prior to delivery to ensure measurement accuracy and reproducibility.
Installation and Training
Our experts install the system at your facility, perform on-site validation and train your operators in load-pull measurement techniques – getting your team up and running as quickly as possible.
Custom Software Development
We develop tailored automation and measurement routines for your specific load-pull, noise and pulsed-IV requirements – from scripts to fully custom test applications.
