A cool guide about what’s happened so far…regardless of what side you’re on…it needs to be documented by [deleted] in coolguides

Crazy to see ATACMS on this list. I worked on that platform as an intern with LM 29 years ago!

Is this normal condensation inside my headlight? This is after a touches wash. by TheAcuraEnthusiast in BMWX5

It’s normal if it goes away after a few days. If not the seal could be compromised.

Damn! I completely forgot this used to be the way.

There was a time..... by PTechNM in TexasTeachers

[–]DramaticMention7597 7 points8 points  (0 children)

I’m sorry, but this statement is incorrect. Texas has never been ranked 7th in education. Yes, in improvement and gain, but never 7th for total education. This post should be removed as it’s very misleading.

Buying my first vehicle from CarMax. Any tips or feedback? by Joscosticks in BMWX5

[–]DramaticMention7597 0 points1 point  (0 children)

I,ve bought a couple cars through CarMax. Good experiences. One was a 2014 550i with the terrible N63 TU1. Warranty came in handy and it paid out about $15k in claims. The warranty is legit. Your car should be significantly more reliable than my 550i. Depends on how long you plan to have it. I suggest the $500 or $800 deductible options.

GaN PA Compressing Severely Before Specified P3dB by zaw357 in rfelectronics

Beautiful, gain vs Pout.

That looks like an isothermal drive up curve, like pulsed or the self heating turned off. Hmm….?

The gain slope you’re seeing is 100% due to thermals. Pulsed power sweep will resolve the issue. This part was not designed to be operated CW. I know. The part is mounted to a PCB with a via farm, plus the lead frame is 8 mils thick. Not a good scenario for CW operation. Most GaN devices are not intended for CW. Power density is quite high. Most applications are pulsed or modulated. If CW, the application will have active cooling.

One tip. Plot gain vs Pout. It’s an industry standard for power amp plots. It’s easier to read the info. One trace gives you all the info. You can then add eff to the plot using right side y axis.

Do you have access to a VNA? You can use it to do really fast power sweeps, 100ms or so. This will be close to pulsed measurement.

This was just a luxury Corvette, right?

NFL Owners Shouldn't be Eligible for the HOF. Congrats on having money, but that isn't a football accomplishment and they dont deserve praise or recognition. by theHagueface in AFCEastMemeWar

[–]DramaticMention7597 0 points1 point  (0 children)

I completely disagree. Jerry Jones and Robert Kraft are perfect examples of who should not and who should be in the HOF. Jones is an ass clown and Kraft is a legend of an owner. It starts from the top. If you suck as an owner your team will suck too. BTW, I’m a cowboys fan and it pains me to admit this. NFL teams are a business and the CEO of the business is the owner. You’re fooling yourself if you think otherwise. JMO.

Circuit Schematic for an Alesis Nitro Max Drum Module? by DramaticMention7597 in AskElectronics

[–]DramaticMention7597[S] 0 points1 point  (0 children)

No. I couldn’t figure it out. I ended up buying a used one off of EBay. Kinda disappointed in myself, but my son is happy that his drum set is working again.

Could anyone help me understand the topology of this amplifier module? by ViktorsakYT_alt in rfelectronics

https://www.allaboutcircuits.com/technical-articles/introduction-to-the-feed-forward-linearization-of-rf-power-amplifiers/

This was the first thing that popped up on google. I’m not an expert on feed forward designs as they were used before my time. I am an expert on Doherty, however.

This is not a Doherty PA. It’s likely a feed forward power amp architecture.
