In the scope of the SOLITONIC project, an analog pre-distortion operating at a center frequency of 300 GHz is developed. Pre-distortion circuits are pre-connected to a power amplifier to compensate for its non-linearity. Several topologies based on class C amplifiers are considered, as shown in the picutre.
The goal of this thesis is to build a parametrized test bench in Keysights Advanced Design System to compare the concepts. You will use available ideal block components. The focus of the thesis should be also on modeling the ideal class C amplifier.

Millimeter-wave (mmW) frequencies are increasingly used in satellite communication systems due to their
ability to support high data rates and bandwidth efficiency. This work will focus on the investigation of
mmW transceivers designed for satellite communication, with emphasis on performance metrics such as
power efficiency, signal integrity, and noise resilience. The student will evaluate different transceiver architectures, analyze their suitability for various satellite orbits and mission requirements, and explore
the impact of environmental factors like atmospheric attenuation. This research aims to contribute to
the optimization of mmW transceiver designs for next-generation satellite communication systems.

The THz-Spectrum is envisioned to play a crucial part in future high data rate point to point links. Scope of this thesis is the setup of Ultra-High bandwidth outdoor point-to-point communication link in THz-spectrum with state of the art communication equipment.

Very Low Earth Orbit (VLEO) satellites, operating at altitudes between 200 and 450 km, offer advantages such
as reduced latency and enhanced image resolution, but also present unique challenges in communication
link stability. This thesis will focus on performing both static and dynamic link budget analyses for a VLEO
satellite. The static analysis will assess baseline link requirements, while the dynamic analysis will
account for variations due to factors like atmospheric attenuation, Doppler shifts, and orbital changes. By
developing a comprehensive link budget model, this research aims to improve communication performance
predictions and optimize VLEO satellite operations.

Our research group develops analog frontends for THz wireless communication systems operating at millimeter-wave (mmW) and sub-mmW frequencies (up to 330 GHz).
In scope of that, several components must be developed, e.g.:
- Amplifiers
- Phase shifters
- Variable attenuators
- Vector modulators
- Analog pre-distortions
