Nujira announced that the company’s Coolteq.h family
of Envelope-Tracking modules now directly interface with Texas Instruments’
GC5322 and GC5325 digital predistortion (DPD) transmit processors and
development boards. OEMs can now reduce operating expenses by more than 25
percent as a result of higher efficiency, improved linearity and reduced system
power consumption over a wide bandwidth in W-CDMA, CDMA2000, WiMAX, WiBRO and
LTE basestations.
The Texas Instruments GC5322 and GC5325 are the first
devices to offer an Envelope Tracking port as part of a package of features to
optimise system power consumption. As of February 2010, TI’s development board
for this family of devices, the GC5325 System Evaluation Kit (GC5325SEK),
supports the Envelope Tracking port and can be connected directly to Nujira’s
Coolteq.h modules, such as the NCT-H4010, which supports average RF output power
levels of up to 60W.
“Texas Instruments is focused on offering our
customers features that reduce the overall power consumption of their systems.
We see Texas Instruments digital predistortion technology and Nujira HAT™
Envelope Tracking technology as key enablers for energy-efficient basestations,”
said David Briggs, general manager of TI’s RF and Radio Products group. “OEMs
can now rapidly deploy these technologies with a minimum amount of development
effort to produce high-performance, power-efficient 3.5G and 4G basestation
platforms that reduce operating costs for network operators worldwide.”
Jeremy Hendy, Vice President of Sales and Marketing at Nujira, added,
“Texas Instruments’ highly regarded DPD solutions work ‘out of the box’ with
Nujira’s Coolteq.h modules, significantly reducing development time and effort
for our OEM customers, and avoiding the need for lengthy FPGA engineering and
optimisation. Using the new Texas Instruments DPD processor and development
board, and Nujira Coolteq.h modules, customers can easily take advantage of DPD
and Envelope Tracking to build high efficiency, high linearity PAs for 3.5G and
4G applications. These technologies can cut the power consumption of the PA by
over 50%, compared to designs using existing power optimisation technologies.”

About
Nujira
Nujira’s mission is to dramatically improve the energy
efficiency of cellular network base stations and digital broadcast transmitters
by reducing the amount of waste energy dissipated as heat in the RF Power
Amplifier. Nujira’s High Accuracy Tracking (HAT™) Modulator technology
dynamically controls the power supply to the PA in line with the transmission
performance required, enabling the creation of highly efficient RF Power
Amplifiers for 3G and 4G cellular networks and DVB digital broadcast
applications.
