Focus Microwaves - DLP Active Load Pull 0.5-40 GHz
Focus Microwaves' DLP (Dynamic Load Pull) is a cutting-edge platform for active load pull measurements, optimized for accuracy, speed, and reliability. Supporting frequencies up to 40GHz and beyond, it offers a versatile solution for CW and pulsed signal applications. The DLP enables fundamental and harmonic tuning, time domain measurements, and advanced behavioral modeling. With integrated options for DC IV and pulsed IV measurements, this one-box system is ideal for all stages of device characterization and testing, from initial development to final product testing. Its intuitive interface and industry-leading calibration techniques ensure precise and efficient measurements.
Active load pull systems are essential tools used in load pull labs worldwide, providing users with the capability to control and adjust impedance for a variety of applications. The DLP system is a fully Vector-based load pull system designed to handle up to 6 loops with 3 harmonics on the load side and 3 on the source side.
In the DLP measurement setup, both forward (a1, b1) and reverse (a2, b2) traveling signal waves are measured using dual directional couplers connected at the input and output of the Device Under Test (DUT) alongside custom receivers. By capturing the “a” and “b” waveforms, Vector Load Pull can calculate the real-time load impedance presented to the DUT using highly calibrated receivers. Utilizing industry-standard calibration techniques, the DLP system generates accurate error correction models essential for precise absolute and vector-based measurements.
Optimized for efficiency and speed, the DLP active load pull system leverages a unique load pull algorithm to streamline the measurement process, reducing the number of iterations required to achieve the target load impedance while maintaining a high level of accuracy. The system has been fine-tuned for simultaneous DC and RF measurements in both continuous wave (CW) and pulsed operation modes.
Furthermore, the user-friendly software interface enhances the overall user experience by providing an intuitive platform for setting up and conducting high-quality measurements efficiently on a daily basis. This user-centric approach ensures that users of all levels can easily navigate the system and perform reliable measurements consistently. The combination of optimized hardware configuration, advanced load pull algorithms, and user-friendly software makes the DLP active load pull system a valuable asset in load pull labs for researchers and engineers seeking precise impedance control and accurate measurements.

More Product Information
The Low Frequency Tuner (LFT) is a unique product technology using M algorithms for low frequency wideband tuning. Three or more cascaded tuning sections use series transmission cables and parallel rotary capacitors. The length of the cables and number of tuning sections are optimized for maximum tuning range over a given bandwidth. HLFT tuners use 6 tuning sections allowing second harmonic frequency tuning.
