i would highly recommend using the Dale/Vishay 1% .5 Ohm 25 watt resitors...
they mount nicely on the heatsink next to the fets and they can take a beating. Only $25 for 10 from mouser.com http://www.mouser.com//index.cfm?handler=displayproduct&&lstdispproductid=379465

heres a pic of how it was done...

Hi Blaine;

I was planning on using the PC board right on the heat sink arrangement as shown on KD1J's web page, I guess these resistors wouldn't fit in that case, correct?

Your parts list is quite helpful. I will compare it to mine to see if your sources are better or less expensive than mine.

No the Dale/Vishay resistors will not work with KD1J's board (unless you JS it together)
the ones used in KD1J's board are 588-TCH35P-0.51 .51 ohms @ 5%
only $7.46 a piece :shock:
The Dale's are .5 ohm @ 1% and cost $2.34 a piece if you buy 10 (you need 8 anyway)
as you can see by the picture most components are mounted on the heatsink, we assembled the op amps onto a small perfboard with minimal components and only 3 wires to the heatsink.

Yikes! :shock: $7.46 each!! :roll: :roll: :roll:

Looks like I'll be shelling out $60+ dollars for resistors! :evil:

Still, I prefer the PC board route, maybe I can get the purchasing agent at work to get me some free samples! :lol: :lol:

Do you know who makes the 588-TCH35P-0.51 T0-220 devices?

Drain Resistors

Postby steve_qix » Wed Feb 12, 2003 10:36 pm

I used the PC board layed out by Kevin (KD1J), and outboarded the FETs and source resistors.

This works very well. I ran wires from the PC board to the FETs. I ran a drain bus for each set of modulator FETs, and connected all of the resistors back to a common point, which became the modulator output. This tied back to the PC board.

So, I was able to use the board where all of the small components are mounted, and run the FETs off-board.

I did this because I was not able to use a flat heat sink for my modulator, and the board requires a flat heat sink if the FETs and resistors are to be mounted on the pc board.

Regards,

steve

Hi KE1GF (name?)

I'm curious about one of the relays listed on your parts list above,

>48V Coil, 240V 10A SPDT Digikey: T7NS5D1-48

Assuming we're talking about Steve's (QIX) designs/schematics, where is a relay being used with a 48v coil? I swear I can't find that on any of the schematics...

Thanks

Hi, name is Bill...

Those relays aren't part of steves design... I'm using them for my tx/rx switching relays and the keying voltage (120v) and I'm powering them with the driver ps (48v)... you could put different relays in their place, like Bob kbw is using some fancy coax switching relay in his design I think maybe you should ask him what he's using to switch his coax relay and keying voltage...

Hi Bill;

RF T/R switching will not be built-in to my Class-E rig. If I only had one transmitter and receiver I might do that, but that's not the case in my shack. I have several rigs besides the Class-E. Last year I designed a master switching / muting box arrangement for my station to allow me to switch between different receiver / xmtr combinations. :shock:
I'm building my Class-E just as it's shown on the QIX schematics

On Steve's schematics, you only need to provide switched 110v for the T/R keying. Since I'm already using a 110v dowkey coax switch, I'll just parallel the wires over from that to T/R switch the class-e rig.

I'm also working on my own parts list that I'll post to the list if anyone's interested. It's on an excel spreadsheet and uses component designations that refer to the KD1J pc boards and schematics. It lists vendor part numbers, quantity, cost, component location, etc..

.001 uf modulator capacitors

Postby ke1gf » Sun Feb 16, 2003 8:25 am

Hi, just to update my parts list and warn you.... don't order the .001uf caps for the modulator using that parts list... THE ONES ON THE LIST ARE SMT CHIP CAPS!!!

Parts list

Postby Phil G4ZOW » Thu Feb 27, 2003 4:54 pm

Glenn,

Go ahead and post that list pertiaining to the PCB kit. I'd prefer to keep things as simple and neat as possible. Boards directly on heatsinks is my preferred route.

Tnx

Those $7.46 resistors...

Postby Kevin » Thu Feb 27, 2003 9:14 pm

...have some competition.

Mouser catalog shows another mfr (Caddock) selling the same
style (TO-220, #684-MP930-0.50) at $3.32 @ 10 price.

Thanks, Bill for the FB Parts List ... saves us all a lotta duplicated effort. Am half-way thru collecting parts ... Boy that Filter Cap bank using the Fair Radio 14000 uf caps sure gets huge ! Let's all be careful with the Energy as well as the Personal Hazards !

Steve, Thanks again for all of your efforts, UR Class E site and this forun are sure a great help fo many of us.

Kevin, those boares are sure beautiful, and will also save many of us a lotta time, too.

TNX for all of the contribution (currently, I am just a sink )
