RF Amplifier Impedance Matching at Microwave and mmWave Frequencies RF Power Amplifier Impedance Matching at Microwave and mmWave Frequencies According to MarketWatch, the overall market for RF amplifiers is expected to surpass $27 billion by 2023. So where are all of these RF amplifiers expected to be used? You can thank 5G and the expansion of cellular networks in general for a healthy portion of the expected growth. For the PCB designers out there, RF amplifier impedance matching becomes an important design point, especially with high power amplifiers. Large-signal RF Amplifier Read Article
Cooling Fan Electrical Noise Reduction in Your PCB Cooling Fan Electrical Noise Reduction in Your PCB Who hasn’t opened up their PC or laptop and taken a long look at its fans and heatsinks? If you’re working with high speed components, high frequency components, or power components, then you’ll need to devise some sort of cooling strategy to remove heat from these components. Unless you want to use the nuclear option and install an evaporative cooling unit or build a water cooling system, you’ll get the best results with the smallest form factor Read Article

Set up a Low Power Rugged Network Attached Storage server Set Up a Low Power Rugged Network Attached Storage Server Building an Internet-of-Things device, or perhaps recording continuous video, requires a low-power, high capacity storage system, preferably utilizing inexpensive hardware. In specific cases, your device might be remote or might deal with high vibration intensities, like being mounted on a piece of industrial equipment, on a robot, or in a vehicle. Such circumstances make solid-state storage indispensable. Raspberry Pi? I started out looking at Read Article
Will All Thin Materials Flex? Will All Thin Materials Flex? Telling “war stories” about flexible circuit designs is something that can provide endless hours of entertainment when you get a bunch of “geeky” PCB people together. In fact, it seems that the best of these stories have all caused countless hours of frustration while in the midst of them, but once that frustration eases, we seem to be able to find both a little (or a lot of) humor in the situation and clarity on the lesson learned. Today, I am Read Article
Designing For The Mil-aero Market—aircraft Designing For The Mil-aero Electronics Market—aircraft In designing PCBs that are used for aircraft delivered to the mil-aero market, there are some similarities to other products within the broader military market sector. Satisfying performance metrics relative to shock, temperature, corrosion, long-term product suppor,t and the ability to adhere to outdated standards and specifications can be challenging in this vertical market space. This article will address these factors and what is necessary to Read Article
PCB Design and Outer Layer Surface Finishes PCB Design and Outer Layer Surface Finishes Although it might seem to be very downstream in terms of overall product development considerations, determining which PCB outer layer surface finish is the correct one is something that needs to be addressed at the forefront of the PCB design process. There are a variety of outer layer surface finishes available with both advantages and disadvantages to nearly each one. Which one is best suited to your particular design is highly dependent on Read Article
