The next generation of linear amplifiers has arrived.

I knew it was well over 8 Volts DC. That's all it would encounter on that chip. Looking at them with a magnifier afterwards found a gap or loose crumbs inside.

How much more than 8 Volts they would take and remain an open circuit is anybody's guess.

The designer claims that other than the PS technology everything else in the box has never been done before. This is huge. This is obviously some kind of break-thru technology and it seems like the CB amp market will move ahead into the future of solid state. No more 3CX3000 amps. This is going to leave the hams in the dark ages. Not really sure which is the bigger and better market.

 

Is there a video yet?

 

Thanks

Looks very interesting.

I'll take one.

 

Hopefully not 3-4 x 90w Targus laptop supplies wrapped up in there.

Sorry had to..

Seem very interesting. I subscribed..

 

Your numbers suggest a power supply with 90 percent efficiency or more.

That's the holy grail now in power supply design. Mostly it's been the battery-power applications where I'm seeing new design tricks for this. Higher regulator efficiency means longer battery life, or a smaller battery to get the same usage level. Higher rectifier efficiency is an even bigger deal for low-voltage stuff. Using MOSFETs switched to make them act as rectifiers is the next big thing. The lower voltage drop is a bigger deal the lower your output voltage is. Makes the design more complicated. Replacing four diodes with four MOSFETs and a controller chip is more complex, but reduces circuit losses.

I'm accustomed to the semiconductor supplier being the party who comes up with new tricks and breakthrough design ideas. A company who invests the up-front cost of developing a breakthrough component that outperforms the competition now has a major incentive. To sell as many of them as possible as soon as possible.

Hence, the Motorola "applications reference" circuits for their RF power transistors back in the day.

I'm a bit surprised that I haven't seen a hint of how you'll do this in Electronic Design, Power Electronics or EDN. That's where new parts tend to be introduced to the world, along with the applications info. Power supply efficiency is a big deal now, especially with the emerging requirements for PFC. That's a wacky thing to achieve all by itself. Never mind how it hammers your overall efficiency.

But unless you have a personal semiconductor factory in your back pocket. the techniques inside your power supply design have probably been broadcast as widely as the parts manufacturer can spread them.

They're interested in "design wins". Persuading design engineers to use their stuff to make breakthrough widgets that will sell by the millions.

So you'll buy their parts by the millions.

Hmm.

If it's truly that unique, consider who will be first in line to buy the first batch.

The ones who want to know what's inside.

the use of mosfets as rectifiers is nothing new.
motherboard vrm have been doing it over 20 years.
synchronous rectification.
