Nujira and Rohde & Schwarz host joint seminars on testing ET for Chinese market
Nujira Ltd., the global Envelope Tracking (ET) chip company, and Rohde & Schwarz, leaders in test and measurement, will be hosting a series of joint seminars in China on how ET improves LTE battery life. The two companies will demonstrate test solutions available for evaluating the PA performance with ET technology and for production testing.
China is an increasingly important market for the growth of ET, as TD-LTE handsets stand to benefit from ET even more than with FD-LTE. TD-LTE handsets can only transmit for 20 percent of the available time, so when they are transmitting they need to use the maximum bandwidth and output power. Tests by Nujira have shown that you can achieve a 40 percent saving in energy-per-bit with ET when transmitting on full speed TD-LTE, even though the instantaneous power consumption during a TD-LTE burst can be double that of FD-LTE transmitting at lower speed. Earlier this year Nujira also demonstrated how its high bandwidth 20 MHz NCT-L1300 ET modulator chip delivered twice the energy savings compared lower bandwidth ET systems.
Highlighting how ET technology is improving the battery life in LTE devices, Julian Hildersley, VP partner development, Graham Teague, sales director, and William Tse, field applications engineer manager for China from Nujira will be speaking about optimizing ET systems and product calibration. Local AE Experts from Rohde & Schwarz, China will also be demonstrating a test solution to evaluate PA performance with ET technology including test setup, calibration data input, FDD test, TDD test, PAE test and ACLR Performance with ET implementation..
Julian Hildersley, VP partner development, Nujira commented, “Nujira and Rohde & Schwarz have been collaborating for many years on advancing ET technology. As TD-LTE networks roll out across China it is the perfect time to host this series of joint seminars, allowing us to come together and demonstrate the full benefits of ET to our Chinese partners and customers.”
The first seminar will take place on September 19 in Shanghai, with two further sessions scheduled for Beijing and Shenzhen. For more information, please visit www.nujira.com.
