No, but it usually takes the 10-14 business days before they ship, so I guess we have to be patient. Usually, they don't even tell me when they ship, so I may not be able to relay much info.. but I'll keep you posted!

Hello ,

Any word on this yet ...........

cviller · 08:27 PM

I asked the company if they could tell me when they would ship and they said they would. I have ordered from them three times before and this how they usually do - not much communication and then suddenly there is a package with some really nice boards!

I ordered right before Christmas, so I'm unsure of exactly how many business days have gone by so far.

A good way to handle this is to provide an area on the board that is basically plated trough holes in a matrix (12 x 12 for example) - like a proto board - so that those who want to put in a cascode circuit can brew up their own, as they wish, proto style... simple enough.

Just an idea...

Thats a good idea, but I think with the bjt setup I landed on, most of the prototyping should be possible without too much effort.

Speaking of which - could you please post again or link again the final schematic and the layout?

I trolled around and am quite unsure what that is - the last i saw was a pdf of a proposed dual jfet cascode input...

I'll deal with whatever it is, but it would be good to clear on it... I'm confused anyhow... but that is easy for me!

Here are the schematics and final layout.

Hello Cviller ,

Looking at the schematics , you have listed boxed stuff is additions, could you elaborate more on this ...

regards,

cviller · 24th January 2010, 05:27 AM

Yeah, the extra stuff is an option for cascoding. With cascoding you can run higher rail voltages. I have also added footprints for extra mosfets so that you can use two pairs instead of just one. If you just want the normal F5, then don't worry about this extra stuff.

BTW: I'm a little bit worried about "regular stuff"...

Any news?
