I'm trying to do some DC/pulse testing on a phemt, partly to validate a Spice model. The RF data sheets are mostly useless for time domain use.
The danged thing keeps oscillating on a regular surfmount adapter, and that makes measurements weird. So I hacked this.
Our general impression is that you can drive these things really hard and get unexpected results, at suitably low duty cycles. We take Abs Max ratings as polite suggestions.
