 Tyco Electronics' Digital Transmitter Technology (DTx) Extends Performance to Multiple Modes and Bands

• Extremely Wide RF bandwidth: Proprietary RF power amplifiers have demonstrated performance from 824MHz to 1910MHz in W-CDMA, CDMA2000, HSPA, WiMAX and LTE modes. The DTx transmitter subsystem enables multiple UMTS bands, including band VII to be combined with quad band GSM/EDGE with no significant cost or size penalties.

• Extremely Wide modulation bandwidth saves money and provides uniform radio architecture: To date polar solutions have been limited to GPRS and EDGE. More traditional IQ designs are required for UMTS, WiMAX, EVDO and LTE. Conventional multimode radio designs require two completely redundant transmitters which doubles size and cost. DTx technology can enable modulation of signals with over 30MHz of bandwidth. This allows energy efficient polar transmitters to scale beyond EDGE to W-CDMA, HSPA, EVDO, WiMAX and LTE.

• Energy efficiency means more features and talk time: The DTx transmitter subsystem provides power efficiency at peak transmit powers as well as superior current consumption at lower transmit powers for all modes from EDGE to LTE. The DTx transmitter subsystem has achieved impressive 40% power added efficiencies in EDGE mode. These benefits can now be extended to even more demanding standards such as HSPA, EVDO, WiMAX and LTE. The energy savings allow additional features or more talk time as well as reduced thermal stress and more compact and flexible board utilization.

• A novel Closed Loop Polar solution provides robust performance for both data and voice devices. The DTx transmitter employs unique algorithms to calibrate device non-linearity in real-time. As a result, performance over temperature, battery voltage, frequency and transmit power is much more tightly controlled. This results in fewer dropped calls, longer talk times and standby times as the adaptive DTx technology adjusts and optimizes performance in real world conditions.

“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.”
