AMCAD Engineering, a pioneer in developing software and hardware solutions for testing, modeling, and simulating radiofrequency electronic circuits, has teamed up with Maury Microwave, the world's leading manufacturer of laboratory devices and system components, for the upcoming EuMW 2023 in Berlin.
Key Demonstrations at EuMW 2023
IQSTAR 1.5 - PA Tests with DPD in Radio-Unit-like conditions
Digital Pre-Distortion (DPD) plays a crucial role in enhancing the performance of RF communications systems. It is a technique used to compensate for the nonlinearities introduced by power amplifiers, improving signal quality and spectral efficiency.
AMCAD will demonstrate a Power Amplifier characterization bench featuring the latest wideband GaN Doherty design from Wupatec.
- Wideband two-stage 8W, 500 MHz iBW GaN PA Design
- Commercial GaN on SiC devices, covering 3.7 to 4.2 GHz
- 47.5 dBm peak power with 30 dB of linear gain
- PAE higher than 42% @8dB OBO
In collaboration with AMD, this demonstration uses the latest Zyn UltraScale+™ Zynq RFSoC DFE and AMD's latest DPD and CFR IP. The bench is controlled using IQSTAR software from AMCAD Engineering, which allows a comprehensive characterization of the RF power amplifier in an environment close to the final implementation of the radio unit.
IVCAD 3.10.2 - Pre-RF Pulse IV Measurements for Enhanced Transistor Compact Modeling
This demonstration focuses on an innovative dual-pulse technique combining a pre-RF pulse and pulse-IV measurements for RF component characterization. These tests are dedicated to transistor compact modeling.
Extracting an RF transistor compact model can be time-consuming and costly. Depending on the project, it can represent several months of work and budgets of tens or hundreds of dollars. Our customers' current need is to speed up RF transistor model extraction.
To this end, AMCAD has developed a new modeling methodology for model extraction. A variable pre-RF pulse shapes the I-V network to obtain a dynamic evolution of the charge trapping state, obtaining a more representative description of the IV curves when the transistor is used in large signal conditions.
These measurements are essential for efficient compact modeling extraction and are dedicated to advanced RF power amplifier design work. This solution uses a VNA-based Load Pull and our AMCAD pulse IV systems to guarantee the perfect alignment of the small-signal and large-signal data used for model extraction work.
Teaming up with Maury Microwave and MPI, AMCAD will demonstrate on-wafer measurements using a Nano5G tuner integrated with the AMCAD Pulsed IV System AM3200 on an MPI probe station. All the equipment will be controlled using IVCAD software.
ATE System - Beamformer Characterization
AMCAD will demonstrate a turnkey Automated Test Equipment (ATE) to characterize Beamformers. The measurement system integrates AMCAD hardware to monitor the measurement conditions and ensure a safe environment for the DUT using very fast e-fuses. At the same time, the test instruments collect the data.
The ATE system is controlled through the IQSTAR platform for complete calibration and characterization. The data is then analyzed with the Whiteboard, using the filters and control tools to identify the important results. The measurements are then used in VISION to extract a model that can be used to simulate an Active Antenna.
VISION 2.3 - Circuit and System Modeling and Simulation
Dive deep into the world of VISION, where behavioral modeling meets simulation, and complexity meets clarity. See firsthand how this powerful platform is reshaping RF system design and simulation.
Modeling PAs and Beamformers: Join us for a demonstration as we model Power Amplifiers (PAs) and Beamformers, breaking down their functionality and impact within RF systems. Uncover the intricacies that drive performance.
Attendees can experience the future of data analysis with AMCAD’s state-of-the-art visualization interface, Whiteboard, and see how VISION transforms complex data into actionable insights. The event will also facilitate the attendees interaction with our experts by asking questions and exploring how AMCAD can elevate their projects.
