RF chips are notoriously hard to lay out, there are a lot of details to worry about: trace widths, via placements, impedance mismatches…so why not use ready-to-go designs? NXP has published a bunch of different RF power amplifier designs. NXP’s RF Circuit Collection is a comprehensive library of RF power amplifier designs, addressing a wide range of fast-growing markets from smart industrial applications to the 5G revolution.
This collection can reduce development time, with easy online access to proven designs for fast time to market. These eval boards are beautifully made, and have easy SMA connectors so you can plug-n-play different amplifiers based on your project need. For example, the highlighted board at Digi-Key is the NXP AFIC901N.
The AFIC901N is a 2-stage, high gain amplifier designed to provide a high level of flexibility to the amplifier designer. The device is unmatched even at the interstage, allowing performance to be optimized for any frequency in the 1.8 to 1000 MHz range. The high gain, ruggedness and wideband performance of this device make it ideal for use as a pre-driver and driver in a wide range of industrial, medical and communications applications.
The eval boards are not cheap – these are really high quality and high precision radio devices for medical, science, telecom and industry. The good news is that NXP has a free site set up to download the designs, so you can learn how RF layout is done, which will help HAMs and other RF engineers. Check it out here.
Adafruit has had paid day off for voting for our team for years, if you need help getting that going for your organization, let us know – we can share how and why we did this as well as the good results. Here are some resources for voting by mail, voting in person, and some NY resources for our NY based teams as well. If there are additional resources to add, please let us know – adafruit.com/vote
