Richardson RFPD (www.richardsonrfpd.com) announced the availability and full design support capabilities for two new evaluation boards from GaN Systems (www.gansystems.com).
The new power amplifiers are designed for the growing wireless charging market and feature gallium nitride (GaN) technology that enables smaller, lighter, lower-cost, and more efficient power systems.
The 100 W power amplifier (GSWP100W-EVBPA) is ideal for applications in the consumer market, including items such as laptop computers, recreational drones, domestic assistant robots, power tools, and fast-charging of multiple smart phones.
The 300 W power amplifier (GSWP300W-EVBPA) is targeted for the industrial and transportation markets for applications including delivery drones, warehouse robots, medical units, factory automation, contractor power tools, eBikes and scooters.
Both power amplifiers offer a range of features, including current or voltage control, built-in protection circuitry, EMI filtering, and configurable output power. The amplifiers combine GaN Systems power transistors with high-frequency GaN E-HEMT drivers from pSemi.
Additional key features of the new PA evaluation boards include:
• 6.78 MHz frequency
• Up to 100 W and 300 W transmit output power
• >90% peak efficiency
• Configurable: voltage mode, current mode, single-ended
• Accompanied by a User’s Guide that includes the evaluation board schematic, circuit description, a quick start guide, and measurement results.
