Universal motherboard and unique daughterboards for evaluation of included GaN E-HEMT performance in any half-bridge topology

Richardson RFPD Inc. announced the availability and full design support capabilities for a family of evaluation boards from GaN Systems Inc.

The GS665XXX-EVBDB daughterboard evaluation kits consist of two GaN Systems 650 V GaN enhancement-mode HEMTs (E-HEMTs) and all necessary circuits, including half-bridge gate drivers, isolated power supplies and optional heatsink to form a functional half-bridge power stage. The kits allow users to easily evaluate the GaN E-HEMT performance in any half-bridge topology, either with the GS665MB-EVB universal motherboard or the user’s own system design.

According to GaN Systems, additional key features of the new evaluation boards include:

  • Vertical-mount style with height of 35 mm, which fits in the majority of 1U designs and allows evaluation of GaN E-HEMTs in traditional through-hole power supply boards
  • Current shunt position for switching characterization testing
  • Universal form factor and footprint for all products

The GaN Systems evaluation boards available now from Richardson RFPD are:
