RF Sensor systems
RF sensor systems use electromagnetic waves in the radio frequency range. They are used in numerous applications to detect objects, measure distances, track movements, or analyze material properties, such as:
- Mobility: for navigation, collision avoidance, traffic monitoring
- Security applications: for motion sensing, presence detection, imaging
- Material analysis: ground probing, non-destructive testing
RF sensor systems can also be used for dielectric spectroscopy, e.g. in
- Smart farming: for plant health monitoring, soil analysis
- Medical testing: for heartrate and respiratory activity measurement
- Environmental monitoring: for identifying microplastics and other contaminants
Wireless Communication
RF systems are the fundamental technology behind wireless communication. They work by encoding data onto radio waves and transmitting them through the air. The technology is used for wireless data transmission in long-range communications, varying from few meters (e.g. Bluetooth) to thousands of kilometers (e.g. satellite links).
Quantum Computing
In quantum computing, specifically for superconducting and spin qubits, RF chips are used for control and readout. They generate and detect the precise microwave pulses (typically 4–8 GHz) that manipulate and measure qubit states. The chips must offer ultra-low noise and high amplitude accuracy, in order to avoid decoherence. They must also consume extremely low power and remain functional in cryocenig temperatures at 4 Kelvin or lower.
