Nujira Ltd, an envelope tracking (ET) technology company, has finalized a funding round that has raised $20 million for working capital to support production plans of its Coolteq chips, and continued development of a long term product roadmap.

Each of the Nujira's existing angel and major investors participated in the round including Amadeus Capital Partners, Climate Change Capital, Environmental Technologies Fund, SAM Private Equity and NES Partners. In addition, Investec Bank introduced new investors to the Company including GAM (on behalf of its GAM Star Technology strategy) and Investec as well as other institutional and high net worth clients.

Tim Haynes, CEO, Nujira said: "Envelope tracking will shortly be a standard component in 4G smartphones and tablets, but we aren't just focused on how ET can be implemented in the latest handsets; we are already working on the next three generations of our ET chips. The company is in a strong position, we have good traction with some world-leading customers and we have a compelling product roadmap. The new investment will be important in helping us execute our aggressive growth plans, as we look to take advantage of our position as the leading authority on ET."

To support its product development roadmap Nujira will shortly be opening a design centre in Santa Clara, California. Adding to Nujira's world-class design team in the UK. The Cambridge-based design centre will focus on the development of next generation ET ICs and will also provide a base for local applications and operations support to US-based customers and partners.

Envelope Tracking is a power supply technique for improving the energy efficiency of RF power amplifiers. It replaces the fixed DC supply voltage to the RF PA with a dynamic supply voltage, which closely tracks the amplitude, or 'envelope' of the transmitted RF signal.
