Key Points
- A power amplifier that can switch operation between Doherty mode and Balanced mode
- Eliminates the need for antenna tuners or isolators/circulators
- Smaller size, lower loss and cost, and reduced system complexity
Abstract
The University of Central Florida invention is a power amplifier that can switch operation between Doherty mode and Balanced mode. The amplifier circuit comprises two amplifiers coupled in quadrature phase through input and output 90-degree quadrature hybrids. This technology is applicable to radio-frequency modules on 4G/5G wireless platforms (for example, smartphones and base stations). Existing technologies based on antenna tuners are not applicable to future 5G systems with antenna arrays, and this limitation can be overcome with the UCF technology.
