RF circuit engineering

In the technical department radio-frequency circuit engineering integrated circuits for radio data transmission in the frequency range of some 100 MHz up to currently 5 GHz are designed and tested. The work comprises a wide spectrum from design of individual RF specific components over the development of RF modules as LNAs and VCOs to transmitter and receiver-circuits. At the metrological characterization and development of evaluation boards we are in close cooperation with the technical department IEM.

Our competencies:

Design, optimization, characterization and modelling of RF specific components (integrated inductors, varactors)
Design of RF modules (LNAs, Mixers, PAs, VCOs, Prescaler, PLLs, …)
Design of complete RF-circuits (PLLs, transmitters, receivers)

Our main research areas are:

Higher working frequencies owing to modern integration technologies
Increasing the integration degree by integration of up to now external components
Integration of case and board modelling into circuit design, modelling of systems-in-package
