LXI™-Certified High-Gamma™ Automated Tuners (HGT™)

MT981HL Series - U.S. Patent No. 7,589,601 B2

Applications & Benefits Overview

Maury's patented (U.S. Patent No. 7,589,601 B2) LXI™ controlled High-Gamma™ automated tuners are optimized for high power in-fixture and on-wafer applications requiring simultaneous sub 1ohm impedance and low vibration. Based on Maury's patented HGT technology, these high-performance tuners evolve beyond multi-probe pre-matching technology to deliver ultra-high VSWR with superb accuracy and reliability.

An integral component of Maury Device Characterization Solutions, these TCP/IP and USB-interfaced automated tuners are controlled using one of four Maury Software Solutions; Maury's MT930 series IVCAD Advanced Measurement and Modeling Software; Maury's Device Characterization Software suite (ATS version 5 or later); direct ASCII command-and-control, or Maury's DLL environment.

With a tuning resolution in excess of a million impedance points and accuracy better than -40 dB over the entire Smith chart, Maury automated tuners give you the device characterization answers you need with the accuracy necessary to make engineering decisions with confidence. Typical applications include load pull using CW, GSM/EDGE, CDMA, WCDMA, WiMax, and WiFi stimulus for mobile and infrastructure terminal design, RADAR design, and Sat-Com design, plus source pull for deep sub-micron CMOS low noise characterizations. Custom Semiflex cable and Cascade-Microtech probe kits are available for optimized low loss on-wafer applications.

The MT981 HGT-series tuner is ideal for load pull, harmonic load pull, hybrid active load pull and all automated tuner applications.

Embedded LXI™-Certified Controller

LXI™ is the power of Ethernet and the Web applied to Test & Measurement (T&M) offering you new possibilities in test systems - local, remote, distributed, time-aware.

LXI™-Certified tuners have many advanced features including: dual TCP/IP and USB interfaces for simple, fast & reliable Control; direct ASCII commands or DLL environment for automated applications; LXI certified for seamless integration with state-of-the-art instruments; and intuitive web-interface for easy tuning.
