Alliance releases envelope tracking design IP to members
June 28, 2011 // Phil Ling
The OpenET Alliance, the not-for-profit industry organisation which aims to drive the adoption of envelope tracking (ET) power amplification techniques in the cellular and broadcast industries, has released key IP design blocks supporting the implementation of the OpenET interface. The IP is now available for free download to new and existing members.
The organisation claims that knowledge sharing is a key element in speeding the adoption of ET and believes the value of the IP outweighs the first year’s membership fees. Developed in VHDL, it comes with a bit-exact simulation and test harness, allowing customisation and verification.
Separate designs have been released to generate envelope reference data from baseband I/Q data for infrastructure and terminal applications. The infrastructure variant provides a digital envelope output, while the terminal variant is structured to drive a parallel DAC.
The Alliance has already released a set of W-CDMA, LTE5, LTE10 and LTE20 test waveform definitions for free download, which support repeatable simulation, measurement and comparison of transmitter performance, and are specified for use in popular EDA tools. Eight waveforms are fully defined, spanning a range of modulation types and channel configurations.
