MMIC amps: Input impedance

I found that common gate or common emitter stages are really useful when pushing the noise figure on wideband amps. That's also how it is done in modern shortwave communication gear where frequency agility all but prohibits the use of tuned circuits.

Certainly. Restaurants can serve excellent burgers. Our favorite is Hangtown Brewpub in Placerville and you can get fabulous garlic fries and a fresh stout or ale with it. Around $8, plus the brew.

What I meant was barbequeing at home. The vast majority merely slaps some pre-pressed patties on the grill and that's what we never do. It is always from scratch.

What sort of wideband nf's are possible? Shortwave doesn't really need a good nf, does it?

Sure. Ground sirloin from not-Safeway.

Don't remember but we came really close to the advertised noise figures of the transistors. It was ultrasound, same range as shortwave but noise really matters there.

Most pathetic was that we were told back at the alma mater that using a FET in common gate is the stupidest thing an RF engineer can do. Of course I did not believe that. Actually I was sitting at the front of the auditorium and to the dismay of the prof I burst into laughter. Couldn't help it because I had just built one for my ham radio station. Then my very first project after getting my degree was, guess what?

The trick is in the spices and dashes of this or that marinade in there. At the end of prep my wife crunches Pringles chips (the spicy ones) by placing them in a bag and running the pin roller over it until pulverized. Then that goes into the meat.

The way be cook them in the barbie they become more round than normal burgers. They also keep really well in the freezer. Problem is, the freezer is in my LAN closet and it's tough to pass by if I know there are some burgers in there.
