With the growing importance of wireless applications and increasing use of wideband, modulated signals, optimizing the linearity and efficiency of amplifiers has become crucial. Traditional passive load pull test benches face challenges such as losses and electrical delay from tuners, cables, and probes, which limit the reflection coefficient that can be provided to the DUT. Advanced mixed signal active load pull overcomes these limitations, presenting wide-range, high-accuracy impedances at the DUT reference plane to evaluate device performance under real-world load pull/source pull conditions.
The MT2000-based mixed signal active load pull demonstration showcases an advanced RF device characterization platform engineered to accelerate the design and validation of high-performance devices for next-generation applications. By combining active impedance synthesis with wideband signal generation and analysis, the system demonstrates precise load pull measurements under realistic modulated signal conditions. Leveraging the MT2000 mixed-signal architecture, which offers up to 1000 impedance/power states per minute with no limitation on Smith chart coverage, users can comprehensively evaluate key parameters such as power efficiency, linearity, noise, and dynamic behavior across a broad frequency spectrum. With a clear speed and accuracy advantage over traditional approaches, this setup is critical for power amplifier design in wireless, automotive, and AD applications.
