LDMOS Amplifier Construction
« on: August 06, 2017, 01:03:40 pm »
A series of eight YouTube videos on the construction of a high power LDMOS amplifier.



This fellow must be very brave or a single man because he joins the two halves of the heatsink together using solder paste and the heat from his electric cooker. If I tried this SWMBO would have words. Also, those transistors are 177 Euro each from Mouser.

I have done the same thing using normal flux cored solder and a cutting torch head to get enough distributed heat but the electric cooker probably yields better results.  I assume the real pros use an argon filled electric furnace.
