RF Devices, Circuits and Materials

Strand leader: Dr Ian Harrison

The current activities of the RF Devices, Circuits and Materials research strand include:

• the design of RF circuits using SiGe HBTs

• the study of extremely high frequency devices

• the investigation into the interaction of optical and high frequency signals using femtosecond lasers and four wave mixing

• the development and characterisation of GaN and related materials for extremely high speed devices and circuits

• the dielectric characterisation of novel ceramic materials
