RF & Wireless Products 900 V SiC Evaluation Kit Components 10 W GaN Amplifier for EW/Radar New 4 W Power Amplifiers for Point-to-Point Applications Richardson RFPD Inc. announced the availability and full design support capabilities for the latest evaluation kit from Wolfspeed, a Cree Company. The CRD-5FF0912P includes two of Wolfspeed’s 900 V third-generation SiC MOSFETs (the 3M0120090J) in surface mount 7L-D2PAK packages. The board allows easy evaluation of the MOSFET switching waveforms, gate drive circuit performance and protection implementation on a PCB. It may be used as an evaluation tool or as a means to quickly prototype a SiC power converter. The evaluation board was designed to demonstrate the superior switching performance of Wolfspeed’s new lowimpedance package with driver source (7L-D2PAK) that was specifically designed for SiC MOSFET technology. The board provides an example of an optimal layout for properly driving the new surface mount SiC MOSFETs with minimal ringing. Additional features of the high-frequency SiC MOSFET evaluation board include: • Flexible half-bridge configuration to quickly prototype a synchronous buck, boost or inverter • 7L-D2PAK packaged C3M SiC MOSFETs with separate Kelvin source • Jumper option for unipolar (15 V/0 V) or bipolar (+15 V/-3 V) gate drive • Test points to easily evaluate Vgs and Vds waveforms, with an option to add a CVR for Ids waveforms • Reliable DESAT implementation • Optimal thermal design featuring an isolated and integrated heat sink with built-in forced air cooling fan ■ Richardson RFPD www.richardsonrfpd.com RFMW Ltd. announced design and sales support for a GaN power amplifier.
