In the last post, I explained my thought process behind designing the low-noise amplifier around the PGA-103+ chip from Minicircuits. I started with defining the specifications, converting those into the schematic, making the PCB...
There are plenty of amplifier designs available online. You can simply purchase one and be done with whatever you plan on doing. However, designing your own low-noise amplifier can be fun. For someone into...
OpenEMS, an open-source tool for simulating electromagnetic structures, has been a valuable resource for the scientific community for some time. Its capabilities continue to expand, thanks to ongoing contributions that add new functionalities. While...
Altium Designer‘s Constraint Manager acts as a central hub for managing all your PCB design rules, electrical properties like trace width, physical dimensions, and clearances. It simplifies organization by offering a table format for...
The AD9913 direct digital synthesizer works as a digital waveform synthesizer that can generate signals with very precise resolution. When it comes to radio receivers, the AD9913 with <0.05Hz resolution can be used as...
It was only through Sadguru Shree Aniruddha Bapu’s arrangement for us to be present as a support function for the “Old is Gold” distribution in remote villages that I had the chance to operate...
I show the process of designing a RF PCB for ADL5801 in Altium Designer. The mixer is part of a multi-channel RF front-end.
The PlutoSDR Rev C brings out both the transmit and receive channels. Thus, making it an even more capable device, especially for advanced RF stuff. A phased array is an advanced RF application that...
Hey there, fellow electronics enthusiasts! If you’ve ever tinkered with the signal generation, you’ve likely come across the AD9833 waveform generator chip. But did you know that this little gem can do so much...
In an article I wrote long time ago, I measured the noise figure of an amplifier using only a spectrum analyzer. The method I used was relatively simple but it took some mathematical understanding...
