What a brutal test of an RF amplifier.

Good video that one. I have always wondered if the XR series is so rugged, would you still need a swr coupler on the amplifier output if it could handle all that abuse?!

Also, if anyone knows, how could you make a 'load mismatch' unit like they use in the video?

Nice Vid!!
Im well impressed with that heatsink they are using! some kinda high efficiency liquid cooled setup!
surely that plays a big part in the device not goin up in smoke!

LJ managed to blow one!

Naughty NXP. The video is clearly a fake. Couple of things...

1. You will note they are using a 1000w power supply to power the amp, watch the video and you'll see it's clearly marked on the HP 6032 front panel. This means unless the amp is more than 100% efficient, then it's not doing 1200w as they claim.

2. You'll also notice the offset value on their Rohde and Schwarz power meter changes 3 times (the minus dB figure to the left of the output power). What this means is they can make it display any value of output power they want. The offset function is designed to account for any attenuation you have in line before the meter, and can be changed to any value you like. For example my test set-up has precisely 50.28dB of attenuation between the N cable and the input to the power meter. If I type in 50.28dB it will read correctly, but if I type in a higher value it will read artificially high.

Undoubtedly these type of new transistors can take some abuse but it's a shame NXP had to produce such a load of shite in that video.

Actually I think the max rating for that power supply is 1200W, but multiple supplies can be linked together on a single control bus to provide increased power output.

But the elephant in the room is the technicians disappearing and being replaced after each test! Were they vaporised?
