Procurement Notes

Verify the specific ordering suffix when purchasing. The suffix '085L0L' indicates bulk packaging, whereas 'TTL' denotes a 100-piece reel. Confirm that the required quantity matches the available packaging format. Ensure compatibility with the recommended evaluation board layout if testing prior to final integration. Check RoHS compliance status as per the manufacturer's current documentation.

Selection Notes

Select this component for high-power S-band applications requiring robust thermal performance and compact surface-mount integration. The device supports up to 1 ms pulse widths and 15% duty cycles. Consider the 50 V typical bias requirement and the need for appropriate ESD handling procedures due to the sensitivity of GaN devices. Evaluate the thermal resistance characteristics for heat sink design.

FAQ

What is the purpose of the VG Sense pin?

The VG Sense pin provides a gate voltage signal that can be utilized for temperature compensation or pulse droop compensation circuits.

How should the device be powered down?

To turn off the device, first remove RF power, decrease the gate voltage (VGS) to the pinch-off voltage, reduce the drain supply voltage (VDS) to 0 V, and finally turn off the gate supply.

What is the maximum junction temperature rating?

The absolute maximum junction temperature rating is 200°C. Operating below this limit is recommended to maximize the mean time to failure (MTTF).
