Palomar 450HD Fet

[truckbeater]

Hi all, Has anybody had any experience with the new palomar Mosfit amp? I am running a Galaxy 94HP and it seems like a good match for me for the input and price range. I have heard that they get warm in a hurry.

Maybe some info here in these discussions

E got it,lol

A lot of good information at the sparky link thank you TonyV
it looks like they get full output around the 110 watt range. I'm still interested in if they tend to get hot quickly.

Most mosfit rigs do tend to run warm, just the nature of that beast so put the fan to it.

Here's some nice pics of one that has a good heat solution. This looks like a COOL setup so to speak,lol the price per watt is awesome! <-- yo gaba gaba. They are going for $245 shipped Palomar FET450HD MOSFET Radio Linear Amplifier Ham CB For Saleat ioffer. best price i have seen.

There you go then.

Wonder how broad banded these mosfet amps are?

60 watts in 400 watts out, if it could work 10 through 80, with a clean signal
cheap 6db of gain.

 

[mackmobile43]

Well that's about 7 to 1 which ain't bad power and 10 meters should not be a problem.

Ive looked at these and wondered aswell.

"Most MOSFET CB Craplifiers do tend to run warm"

There, fixed that for ya Mack. NONE of my RF FET amps run warm at ALL.

It's this switchmode garbage that people think works on the CB that runs warm. Running a device into saturation will ALWAYS cause that to happen

As 443 pointed out as well, as the FETs heat up, Pout will DROP!!!!
