Rapid VT Active Load Pull by Focus Microwaves

Load-pull test is crucial in RF front-end validation, ensuring proper device characterization under real-world conditions. It can ensure efficient operation, maximum power transfer, and overall optimal conditions for operation of a given device. However, load-pull test is often complex to properly set up. It can involve components including tuners, couplers, and RF instruments and can be difficult to test quickly, in a cost-effective manner, and with meaningful data insights.

 

​​For a solution to meet these demands, it must meet the following requirements: 

 

  • ​Ensure standard-compliant signal generation and analysis for modern, wideband waveforms for Wi-Fi 6/7 and 5G NR
  • ​Allow for S-parameter and modulated measurements on the same test bench
  • ​Be able to test across design, verification, and production test applications
  • ​Enable quick test configuration, fast measurement speeds, and lower overall cost of test

Rapid VT Active Load-Pull Solution Overview

  • Based on the NI PXI platform for increased test scalability and versatility
  • Support for the latest 5G NR and IEEE standards
  • Combines both S-parameter and modulated load-pull measurements
  • Up to 1 GHz active load pull bandwidth capability with NI PXI Vector Signal Transceivers
  • Can be used in all parts of the design cycle, including initial device characterization, MMIC or PA design, design verification testing, and production test

Solution Advantages

  • Lower overall cost of ownership with a versatile hardware platform and reuse across design, validation, and production test applications

  • Increased throughput with fast test configuration and measurements

  • Streamlined validation processes with PXI VSTs that can be reused in the lab for other RF test applications such as DPD, ET, and general RF measurements

  • Future-proof and scalable test systems through modular and upgradeable PXI instrumentation
