More about the webcast
GaN transistors have proven capability for the realization of high power Solid State Power Amplifiers (SSPAs). At lower RF frequencies unmatched packaged transistors can be used but as operating frequency and output power increases pre-matched transistors or MMIC amplifiers are a more practical solution.
This webcast presents the design of a 100W X-band PA using bare die discrete GaN transistors from Cree. This approach is a useful alternative to using pre-matched transistors or MMICs. It allows the implementation of a compact, high power design using Commercial Off The Shelf (COTS) transistors. The webcast will cover the following:
- Modeling the individual power transistor
- Top level topology for the 100W design
- Detailed design of matching structures
- Design of the gate and drain bias feeds
- Ensuring amplifier stability
- Optimising for output power
- Design of driver stage
- Simulation of the complete amplifier
