by Graham Pearson and Liam Devlin, Plextek RFI Many emerging applications at Ka-band and above, such as 5G and broadband satellite communications, are adopting architectures that require low-loss, high-linearity switches. FET-based switches on both GaAs and SOI (Silicon on Insulator) are used to realize high performance, low-loss switches at RF frequencies. They have been used […]

by Andy Dearn and Robert Smith – Plextek RFI The scope and performance of commercially available Gallium Nitride (GaN) discrete transistors is steadily increasing and the parts now available from leading manufacturers have impressive RF performance in terms of their available gain, RF output power and efficiency. For RF output powers in the order of […]
