Comsys Mobile and Rohde & Schwarz Deliver Optimized WiMAX/GSM-EDGE RF Calibration for Mass Production

(Business News & Technology News, 4 Jun 2009)

Comsys Communication & Signal Processing Ltd and Rohde & Schwarz has jointly developed a customized test solution for RF calibration offering customers the most cost-effective test solution for RF testing, calibration and signal testing in devices incorporating Comsys Mobile’s ComMAX CM1125 mobile WiMAX/GSM-EDGE modules.

This highly optimized solution is based on Rohde & Schwarz RF production testers into which the ComMAX SoC testing scheme was ported and fully optimised for automated testing. The solution combines alignment and verification with maximum throughput tests in a single box for production-line emulation of a base station. Test engineers are able to quickly build a competitive test platform to test their new designs, while manufacturers are able to automatically align transmitter/receiver functions such as frequency response and linearity. This enables quick ramp-up of the production line and maximum throughput.

For mobile WiMAX RF calibration, the R&S CMW270 was chosen. This is a very fast one-box tester for the production and R&D of WiMAX mobile stations. For GSM/EDGE RF calibration, the R&S CMU200 was used. This is a market established mobile radio tester for production as well as R&D.

Comsys Mobile’s ComMAX CM1125 single-chip multimode mobile WiMAX/GSM-EDGE baseband processor features full mobility support, low power operation and integrated support for legacy cellular networks. ComMAX CM1125 comes with a unique multimode handset reference design platform enabling rapid development of converged mobile WiMAX/cellular devices.

“We‘ve carried out many fruitful projects with Rohde & Schwarz, and we’re delighted to have such a high-calibre company as a ComMAX ecosystem partner,” said Mr. Avi Sharon, Director for LTE Product Marketing. “Comsys Mobile is constantly striving for ways to make it simple for manufacturers to integrate our mobile WiMAX solutions, and we have achieved this most effectively in our joint solution with Rohde & Schwarz for RF testing & calibration.”
