Tyco Electronics has announced successful demonstration of its innovative multi-mode DTx technology, which provides a single transmitter solution for GPRS, EDGE, CDMA2000 and UMTS. The DTx technology is a radio architecture that enables true multi-band, multi-mode operation from 2.5G to 4G with a single closed loop digital polar design. Having demonstrated power efficiency in all the 2.5G and 3G standards, the DTx technology provides an ability to extend the benefits of a polar architecture to WiMax, LTE, EVDO and High-Speed Packet Access (HSPA) networks.
Based on novel circuit and signal processing techniques, DTx technology includes a full transmitter subsystem with robust calibration and corrections algorithms."The DTx technology platform that is now in demonstration brings significant innovation to support true multi-mode capability, creating a preferred path to a common radio architecture for the multiplicity of voice and data modes and bands," said Finbarr McGrath, director, DTx Technology, Tyco Electronics. "The DTx technology extends the benefits of closed loop Polar Modulation from GPRS/EDGE through W-CDMA, HSPA, EVDO and beyond to LTE and WiMax. This will allow for cost effective production of multimode radios as well as providing additional space and reduced power consumption for the features that will be required in smarter mobile devices for today and the future."
