Broadband vector network analyzer addresses demanding mm wave test applications

March 07, 2007 | | 197800731
The redesign of Anritsu's VNA provides the industry with the highest output power to drive active and passive components at optimum measurement levels and an improvement in calibration stability also means that the most demanding measurement needs will now be satisfied by the broadband VNA.





Anritsu has enhanced its Lightning Broadband ME7808C vector network analyzer (VNA) for characterizing devices over a wide 40 MHz - 110 GHz frequency range. Enhancements include improved calibration stability and higher output power to drive active and passive components at optimum measurement levels.

Engineers can realize more accurate analysis on their devices, whether it is coaxial or demanding on-wafer environments, by using the ME7808C. Among the design enhancements made to the ME7808C are relocating the couplers inside the multiplex combiners, improved Kelvin design bias tees, better RF and LO stability, and greater short-term and long-term calibration and measurement stability. The system now includes an option providing direct access to the samplers for improved raw directivity and calibration while optimizing system dynamic range.

The new multiplexing coupler/combiner allows all essential DC signals and RF sampling to be in close proximity to the device under test (DUT), further improving raw directivity as well as increasing measurement system stability. Designed into the multiplexing modules are the Kelvin bias tees for enhanced performance and sensitivity. The ME7808C has also been designed with improved phase stable cables for better calibration and measurement stability.

The ME7808C delivers significantly improved performance due to the enhancements. It can provide up to -13 dBm of power across the entire 40 MHz - 110 GHz frequency ranges, which is 9 dB better than competitive models. Power output is a significant factor in measurement accuracy because losses between the coax output port and the probe tips can be dramatic.

Another advantage of the ME7808C is that Anritsu includes System Assembly and Verification service at no charge. With the service, customers are ensured that the system will be operational and verified for expected coaxial performance and accuracy in a minimal amount of time.

The ME7808C can be configured for three completely independent configurations; 40 MHz - 110 GHz 1 mm broadband coaxial systems, 65 GHz V connector coaxial systems, and 65 GHz to 110 GHz extended W Band waveguide mm wave system. The system may also be upgraded to include a full range of banded mm wave modules, which can be used to extend the frequency range beyond 110 GHz in stand-alone waveguide bands. In addition, it is now possible to extend the maximum waveguide frequency range up to 500 GHz in WR-2.2 waveguide.

READER OFFER

This month Keithley Instruments is giving away two of its Model 2200 power supplies, worth 735 Euros each, for EETimes Europe's readers to win. The Model 2200-20-5: 20V, 5A, 100W on offer is one of five general-purpose programmable DC power supplies recently launched by the company, designed for source measurement instruments for component, module, and device characterization and test applications.

Part of the Series 2200 family, the unit’s voltage output accuracy is specified at 0.03% and its current output accuracy is 0.05%. The supply’s high output (1mV) and measurement (0.1mA) resolution makes it well-suited for characterizing low power circuits and devices in applications such as measuring idle mode and sleep mode currents to confirm devices can meet today’s ever-more-challenging goals for energy efficiency.

And the winners are:

In our previous reader offer, EPC was giving away ten of its EPC9002 development board kits, worth USD 95 each.
Lucky winners include  I. Blythe and C. Hardman from the UK, M. Casartelli and D. Cogliati from Italy, C. Cossio from Spain, W. Milarch from Germany, r. Milewicz from Poland, M. Prascak from Slovakia, A. Raidl from Austria and M. Taslakov from Bulgaria.
All should be receiving their kits soon. Let's wish them some interesting findings with their projects.
