Where to get blob board?

Maybe he saw your picture? and decided to just give up on the whole thing!

Bellin?

But I agree with Win, you should be sent to breadboard boot camp.

Everybody's a critic.

That's a 12-GHz pHEMT cascoded by a 45-GHz SiGe:C NPN. Size matters.

The visible circuitry is all biasing and stuff.

it'll probably take 10 minutes to layout and JLPCB will do 5pcs 100x100mm boards for $2

Haha, I'm sure Phil can show us nice SMT examples.

But I'm wondering about good pad size / spacing for SMT projects. 0.65mm pads with 0.95mm spacing handles SOT-23, but we also need 0.5mm spacing.

Someone I worked with used to refer to these as 3D RF structures, mostly because he could have used them as a Theremin.

I've seen a number of very pretty-built prototypes (maybe even built a few myself) that don't work worth a damn because current cares about loop area not winning the beauty pageant!!!

Take your pick:

Although a lot of them are non-stock so you'll have to wait a bit for the finer pitched kind, by the looks of it. I'm sure there are better sources. Adafruit or Sparkfun may stock them?

The stuff I've been using is 0.5 x 0.65 mm, which works pretty well.

The only ones in stock are 0.1 inch pitch.

REALLY! I mean, I've made some crappy looking breadboard monstrocities, but my EYES still hurt after that one!

Looks okay to me for a proto. The ebay guy went out of business because somebody better and probably bigger jumped in the game at a cheaper price point.

These guys might have something that will work. I have not searched their site in a while

Element 14 (used to be Farnell/Newark) seems to have lots. They call them "matrix boards". Here's one example.

There seem to be 52 others, all with holes for leaded components.

Throwing "smd" into the search string produced 70 items. Here's one of them.

How about coming up with a proto type board with an area for bias circuits and an area for RF circuits with some test points for at least the bias circuits.

And then license the design to someone to sell your prototype boards. It does not eliminate your having to layout a board, but it might pay for the annoyance. And you get some boards that hopefully are better than anything on the current market.

When life gives you lemons, make lemonade.

Agreed. Puts *my* efforts to shame! :-D
