GaN-based digital transmitter architectures for 5G
/forschung/publikationen/gan-based-digital-transmitter-architectures-for-5g
Fully digital transmitter chains are an important step towards the software-defined radio. Digital amplification is obtained by encoding the baseband signal into a binary bit stream and amplifying…
Novel approach for E/D transistors integration in GaN HEMT technology
/forschung/publikationen/novel-approach-for-ed-transistors-integration-in-gan-hemt-technology
The purpose of this work is to introduce a novel concept for integrating enhancement mode (E-mode) and depletion mode (D-mode) AlGaN/GaN HEMTs in the same fabrication process. Unlike existing E/D…
Effects Degrading Accuracy of CPW mTRL Calibration at W Band
/forschung/publikationen/effects-degrading-accuracy-of-cpw-mtrl-calibration-at-w-band
On-wafer measurements of a Device Under Test (DUT) can yield accurate results only if the properties of the measurement environment are well defined and unwanted effects can be removed from the data.…
Load Tuning Assisted Discrete-Level Supply Modulation Using BST and GaN Devices for Highly Efficient Power Amplifiers
