 on NPI. Okay, we're not stopping. We're gonna we're gonna keep checking this out because every week there's new stuff. There's new stuff and this is a partnership at Digikey. New stuff every week. New products. Your NPI. New product. Introduction. Introduction. Okay, I'm gonna grab my notes. What is this thing? Okay, so this one is actually interesting because last couple weeks we've picked chips or components or sensors or something and this week actually wanted to feature some of the educational resources that you could also get with new products. New products are just about products. I know you're like but products in the name. It's also about resources for engineers and this is actually something I would have found really handy when I was designing the wave bubble. So if you've ever done or wanted to do RF circuitry, you know, you have to change the way you lay out your circuits. You can't just eat a plot part on where you want and connect traces, you know, the fitness trace you can get, send it out to Oshapark and hope that you get the best performance. For a lot of these parts, especially as you're getting into, you know, 100 megahertz, gigahertz plus range, the type of PCB, the way you lay out, the components you use is really important. So this week's IMPI is gonna look at a nifty collection of RF reference designs and deval boards that are published by NXP. So it's NXP slash free scale. They have a bunch of like really intense powerful amazing RF chips. They use in science, military, medical, you know, all kinds of technology, cellular, telecommunications. So you're trying to basically make chips that can like, you know, beam data around really, really fast and you want to get the best possible performance, especially since, you know, your link budget is limited either by, you know, your power availability or your antenna or your legal limits or whatnot. So they, you know, there's a bunch of eval boards that are available. So this one is the AFIC 901. It's a two-stage high gain amplifier. You can see there's an input SMA, output SMA. It's like a beautiful ceramic PCB. These aren't inexpensive, but, you know, if you really want a val board, you don't want to spend the time getting this like ceramic piece together and like bolting it on. These are really nice little plug and pay pieces. And then when you go to NXP's website, you can see they have, you know, data sheets and DXFs of all the layout information. And I like how they're really clear about exactly where you want to put every part, you know, what's the component values, how far it has to be away. It's not, you know, the one I downloaded, it wasn't like an Altium file. It was a DXF, but it still had enough information that you could duplicate it into your design. So you can use this as a little building block, a proven RF design, so you don't have to worry about like, oh, what if I didn't do a perfect job because RF is so tricky to get right. Little things, you know, the twist of an inductor, the thickness of a trace can make a huge difference. To see, these are some of the other eval boards available. They also like look really cool. These are like beautiful designs. I think I saw, you know, there's this eval board for this two gate amplifier. There's about 400 designs for download from NXP. So, you know, you have to register, but it's free. Some you have to request, maybe because there's some export compliance or because of the technical requirements. But I saw like 50 of them were downloadable and I just started picking through them. I was learning a lot about different layouts. Now, if you want to get it, you can type in this code into Digi-Key site. You can search for it in the ways that they did. But this is the Digi-Key part number and they also have a section. This is the website. So this is what I was interested in. I was like, oh, this is a kind of handy. It's like, you know, all these little gain stages and amplifiers and maybe splitters, PLLs, all that stuff. So check out NXP. They make a lot of good RF chips. And that is IONMPI.
