"Problems are not stop signs, they are guidelines." Robert H. Schuller

The story

KoalaTech (KT) is a young and dynamic European startup high-tech company created in October 2018 as a spinoff from Nova University of Lisbon and with the support of an investment fund (SMENT Digital), focused on the design of Radio Frequency transmitters to solve the lack of energy efficiency and security on wireless communications systems (5G and Wi-Fi 6), both public and military. KT’s mission is to reduce the huge amount of wasted energy in present and future wireless communications, contributing both for reducing the operational costs and achieve eco-sustainability in telecommunications. KT revolutionary technology creates a disruption over traditional Radio Frequency Amplifiers and opens a way for a new level of energy efficiency in telecommunications, with energy consumption reduction by a factor of 4 times. This new paradigm is based on 10 patents that resulted from the R&D conducted by KT Founders and team in the last years. First proof of concept prototypes with discrete components show energy efficiencies higher than 50%. Higher efficiencies are excepted with the optimized chips that KT is currently developing.

The future

In the near future our goal is to extend KT technology to millimetric waves and future 6G systems. QDA extension to Satellite communications in Ku and Ka bands are also aligned with the strategic R&D lines envisaged by KT.

The founders

PhDs in Electrical Engineering and more than 20 years of experience in R&D in telecommunications and microelectronics of most of the founders are the base for the excellence of the technology developed by Koalatech.
