GaN Systems has added a 50 W wireless power amplifier - a small size, low cost, and high efficiency evaluation board ideal for wireless power transfer and charging applications – to its family of wireless power transfer products. It is targeted for lower power applications in industrial and consumer markets for items such as power tools, IoT devices, handheld terminals, medical devices and household robots.

This evaluation kit adds to GaN Systems’ solutions that include the 100 W power amplifier and 300 W power amplifier that are designed to support, simplify, and speed up the innovation of wireless power transfer systems. These kits combine GaN Systems power transistors with high frequency GaN E-HEMT drivers from pSemi and are designed to be consistent with AirFuel standards.

The 50 W evaluation kit addresses challenges associated with working at high frequency, which provides an easy-to-use baseline for engineers in their system designs.

The evaluation board uses GS61004B E-HEMTs in a 50W 6.78MHz class EF2 power amplifier.

Key features of the GSWP050W-EVBPA:

  • Constant current mode
  • Push-pull
  • 100V / 45A, 15mOhm GaN E-HEMTs
  • High speed GaN driver
