Gennembrud for ny RF-teknologi i mobiltelefonen
En af verdens fem førende mobiltelefonproducenter vælger at integrere Coolteq-teknologi, der baner vejen for at opbygge langt mere effektive PA-trin (in english).
The UK-company Nujira today announced that a major global OEM has signed a purchase agreement for its Coolteq-l handset development platform, the first since the technology was announced at Mobile World Congress in February 2009. The name of the OEM, one of the world’s top five handset makers, was not disclosed.
Prior to purchasing the development platform, the OEM conducted an in-depth assessment of Nujira’s Coolteq technology; the results of this assessment matched Nujira’s own claims for the technology.
Commenting, Tim Haynes, Nujira CEO says:
- This is the first time Coolteq-l has been independently assessed by a major handset OEM and we are delighted that our own measurements of the power consumption and bill of materials advantages have been confirmed by our customer. Since announcing our handset technology at MWC we have experienced enormous levels of interest from multiple areas of the handset supply chain including the OEMs themselves and expect other deals to soon follow.
Test results show that a handset PA using Nujira’s Coolteq-l with embedded HAT technology is twice as power efficient during HSUPA transmissions, and 1.5 times as efficient during W-CDMA transmissions compared with the same PA without Coolteq-l. The benefits are even more pronounced as data rates increase and the technology is thus highly applicable for future LTE handsets.
Nujira Coolteq-l enables the creation of an efficient wideband RF front end, covering three to five times the bandwidth of a standard design with up to double the efficiency. Only two PAs (power amplifiers) would be needed to design a front end covering all of the fourteen different frequency bands defined in the 3GPP for LTE and all of the operating modes (GSM, EDGE, WCDMA, HSUPA and LTE), compared with seven or more without Nujira’s solution thus achieving a significant reduction in the handset Bill of Materials.
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 circuit. Nujira High Accuracy Tracking (HAT) Modulator technology dynamically controls the power supply to the circuit 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 transmissions.
