Evaluating GaN power amplifiers typically involves multiple boards, external matching circuits, and protection components. Complex test setups and repeated tuning cycles are also needed. To simplify this process, RFHIC offers Integrated GaN Evaluation Board (EVB) solutions. These provide a compact, ready-to-use platform for testing high-performance GaN RF transistors and amplifier stages.
Integrated Architecture for Compact RF System Design
RFHIC’s EVB integrates the driver stage, main GaN-on-SiC power transistor, circulator, and feedback circuitry on a single board in a fully matched 50-Ω design. This compact architecture reduces the need for external matching networks and additional components during amplifier evaluation, simplifying RF chain development. By consolidating key amplifier stages and protection elements into one board, the EVB reduces RF validation effort across multiple stages and helps maintain consistent measurement conditions.
The integrated EVB platform provides several practical benefits for RF amplifier development:
- Reduces time required for RF performance validation across amplifier stages.
- Fully matched 50-ohm input and output interfaces for straightforward testing.
- Supports digital predistortion (DPD) evaluation, including validation with platforms such as MaxLinear and AMD.
- Enables testing aligned with FCC linearity requirements through DPD optimization.
- Supports multiple frequency bands and output power levels for telecommunication infrastructure.
Turn-Key Platform for O-RAN Radio Development
Designed for O-RAN radio unit development, the EVB provides a ready-to-evaluate RF amplifier platform. By integrating the driver stage, GaN power device, circulator, and feedback path, the board reduces design complexity and supports faster prototyping for 4G and 5G base station systems. Its compact form factor also supports efficient RF system layouts while allowing engineers to evaluate power efficiency, linearity, and overall amplifier performance before final hardware integration.
