Innsystec, a spin-off ofRWTH Aachen University (Germany), has invented a new solution for highlyefficient and linear HF transmitting devices which encompass the fundamentalsfor further ongoing development. In the seminar the Innsystec team will presenta technology that is tackling the issues of envelope tracking.
What solution is Innsystec aiming for?
Innsystec has come up witha new transmitter architecture based on the multi-level outphasing technology.It is a complete transmitter including the RF power amplifiers. Innsystec’stechnology can be brought into various applications ranging from base stations,small-cells, WiFi for access points and mobile applications, also for 5G basedon massive MIMO solutions. The following figure shows the general block diagramof the solution:
What are the advantages of the solution?
The following figuresummarizes the advantages of Innsystec’s patented approach which can be reachedwith an integrated circuit-solution:
Who should attend?
The technology is veryflexible and can be used in all types of wireless transmitting devices. Innsystec’ssolution will be implemented in an integrated circuit (IC). Everyone who isworking in these fields is welcome to join.
