Nujira has worked closely with the MIPI Alliance since the formation of the ACI Working Group in November 2011, contributing to the development of a standardised specification that provides interoperability between multiple 3G/4G modem chipsets and Envelope Tracking Power Supplies (ETPS).
The eTrak specification, which has already been incorporated by multiple modem and ETPS vendors, allows dynamic control of the supply voltage of RF power amplifiers, which improves the efficiency of the transmitter, one of the three large power consuming elements in a mobile device. The specification enables vendors to work effectively with one another while giving OEMs confidence that the components needed to create leading-edge products will be available from a number of sources.
Nujira’s own NCT-L1300 ET power modulator is already designed to be compatible with the eTrak interface, which supports the full 20MHz bandwidth required by 4G LTE.
Tim Haynes, CEO commented: “Nujira is proud to be a contributor to the eTrak specification, and believes that open standards like eTrak are integral to the future success of Envelope Tracking. The highest system performance can only be achieved with the right interface, and we welcome the introduction of products that unlock the full performance potential of Envelope Tracking.
“We fully expect ET to achieve a 100% attach rate in smartphones and other categories of wireless devices in the next year, which would simply not be possible without the work done by the MIPI Alliance in producing the final specification.”
The eTrak specification is available for members to download from the MIPI Alliance website and is available under MIPI Alliance IP rules.
About Nujira
Nujira’s mission is to dramatically improve the energy efficiency of transmitters for 3G and 4G handsets by reducing the amount of waste energy dissipated as heat in the RF Power Amplifier circuit.
Nujira’s patented Coolteq® Modulator technology dynamically modulates the power supply to the circuit in line with the amplitude of the signal, enabling the creation of highly efficient RF Power Amplifiers. Today Coolteq technology powers the industry’s most energy efficient and highest performing 4G base stations and TV broadcast transmitters. Nujira is now applying the same energy efficient technology to smartphones and other portable wireless devices.
A fabless semiconductor company located in Cambridge, UK, with design centres in Cambridge and Edinburgh, Nujira is enabling the design of cost-effective multi-mode, multi-band handsets that deliver faster data rates, longer battery life, and better coverage.
