Quantance Claims Big LTE Handset Performance Gains with ET Chip

Quantance, a venture‐backed semiconductor startup based in Silicon Valley, has begun sampling its third‐generation chip to several major players in the LTE supply chain, including baseband/transceiver chipset providers and handset OEMs. Envelope tracking provides power amplifier efficiency and transmit power improvements. This enhances battery life, reduces heat and helps deliver maximum 4G/LTE wireless system performance.



Quantance claims its patented "qBoost" envelope tracking (ET) technology enables power amplifier (PA) efficiency to reach theoretical limits, and at the same time, dramatically increases PA transmit power. The Q845 chip supports ET operation up to 20MHz LTE, providing the response time equivalent of a 400MHz switcher for ET systems. The company said its Q845 chip is more than 100 times faster than any other mobile ET power supply solution available today.



Investors in Quantance include TD Fund, Granite Ventures, InterWest Partners and DoCoMo Capitalhttp://www.quantance.com

  • Quantance was founded in 2006 by Vikas Vinayak and Serge Drogi, both of whom previously worked at Maxim Integrated Products.
