I'm always intrigued and puzzled why so many hams place so much reliance on inherent brute force device survival per se when placing their amplifiers through this kind of severe load and phase angle
Leigh, the idea of having a device without external means for protection is intriguing. A device that can sustain such repetitive abuse and continue to operate is really something. As you said stated
Yes I do concur here George; that's an impressive device survivability capability all right! Nevertheless, as an amplifier designer using this device I'd still build-in the aforementioned ancillary s

The video is, indeed, impressive - but it could also give a false impression. The transistor operating spec. is 100us pulses at 20% duty cycle - 100us on, 400us off. Looking at the current drawn duri

Yes, there's no doubting that these modern FETs are generally quite robust. For most amplifiers there's a range of phases of high VSWR where they will survive ok, and a smaller range where they are m
Your so right Leigh, isn't it nice to see a high power semiconductor that gives you a moment to react before shutdown or taking corrective action without destruction. 73, George, K4GVT Nevertheless,
Very nice project, nicely built and quite the survival test. Thank you for sharing the data and great pictures. 73, George, K4GVT On 3/11/2013 4:14 AM, Peter Frenning [OZ1PIF] wrote: Den 11-03-2013 0
