Duotech Ask an Engineer PostsRadar Signal Chain Discussion
What does a generic radar signal chain look like? What are the considerations that come into play?Watch the video below.Previously, we have talked about technical basics such as Noise Figure, Phase Noise, Antennas, and other topics. What does a larger system design...
Noise Figure – WATTS Relevant
Video: Noise figure is a key parameter in understanding RF systems and negatively impacts their performance. What does it mean? What are the implications? How is it measured? Watch to see how this specification impacts both radar and communication systems. Also, this...
Tubes vs GaN – Video by Daniel Rogers
Video below - Are you considering a move from TWTs or other vacuum tubes to GaN? Duotech has decades of experience moving customers to GaN/GaAs devices from older electronic devices. Making the choice about application, environment, and cost are critical. If you are...
Transient Current Events in DC Motor Drivers
Brushless DC motors advantages for new designs or redesign of motor actuated systems. These include more reliable and longer sustained mechanical systems, but what are some of the electrical implications of designing a brushless motor? We offer a wide variety of...
What Makes an AESA Radar Better? AESA Radar Advantages
Not only are there space and weight savings because of the Integrated transmit and receive chain, an AESA radar provides opportunity for many performance improvements over a mechanically scanned radar antenna. This video discusses a couple of them. The high movement...
Antenna Arrays Pt. 2 with Silas Gibbs
The concepts of phase shifting antenna elements to create a high-gain antenna can be extended to allow digital control of the antenna direction in what is known as an Electronically Scanned Antenna. Electronically scanned antenna arrays use phase shifting elements to...
Antenna Arrays Pt. 1 with Silas Gibbs
Directional, high-gain antennas can be made using arrays of individual elements rather than through large horn or parabolic antennas. Individual radiating elements with controlled phase shifts combine to create more gain in a desired direction. Initially arrays of...
Antenna Elements to Antenna Arrays
This video below discusses an individual antenna element, an array (e.g. leaky waveguide, PESA, AESA). What role does phase shift play in a system and the idea that relative distance and element size is related to frequency. We encourage you to pass this video along...
Filters – the terminology and operation of filters
Understanding frequency selective services requires specific domain knowledge. This video provides an overview of filtering basics beyond just know if your filter is low-pass, band-pass, high-pass, or notch. How quickly does it roll off? How far into the stop band...
FPGA vs Microcontroller – Advantages of Using An FPGA
What is an FPGA device? A Gate Array is a prefabricated semiconductor device, like a silicon chip, that has not been configured to have a particular function during fabrication. The Field-Programmable Gate Array, or FPGA, is an integrated circuit that can be...
Software and Driver Development – Whiteboard Video
[Watch Video Below] When adding hardware to a primarily software project, drivers are required to expose the hardware to the applications and operating system. Duotech has the experience and capabilities to write custom drivers for your project. Contact Duotech with...
Fun With Fabrication – We’ll Show You Ours If You Show Us Yours
Need something created like a custom glass and metal table for an office space? How about a steel canopy for your carport? Maybe you have an idea for a birthday present to build a roll cage frame, weld it onto a go-kart body, and then mount it to that old 3.5 HP...
