Any company producing an SS amp running 1.5Kw out with just one of these LDMOS devices are idiots. Everybody but SPE are using two. I just looked at the price for a new matched pair of RF Parts 3-500ZG's. $400.

Danish embroidery thread/The amplifier is a push-pull design, using a dual-LDMOS device; by nature, this type of amplifier does a good job of suppressing even harmonics, but the odd harmonics are monsters, so be sure to use a good low pass filter. Just look at this spectrum analyzer display of the unfiltered output on 40 meters:

/Dec 15, 2011 · It finally happend… After a decade of reliable service, my Alpha91b amplifier broke. Most likely on it's way to Spain one of the tubes broke. During the comissioning at ED1R, fire & smoke shot out of a chimney. The first shock was big, but a few measurements confirmed that just the tubes were broken. In this blog post I will share the knowledge I gained during during debugging, comissioning ...
