Recently in Penang, Malaysia, there was a protest against allegedly 5G Telco towers that were being set up inside residential areas. The concern was that with the new telco towers in so close proximity to the water supply and houses, it would pose a greater cancer risk to the residents in that area. The state …
How to Design Impedance Matching
When designing schematics, impedance matching is an importance process to ensure minimum loss of the design. When a schematic is mismatched, it will result in high reflection of the input signal, this would translate into transfer loss. A schematic that is matched will ensure the lowest possible loss theoretically, that is maximum power transfer. When …
Review of IMESS 2019
Beginning in the year 2016, the IMESS 2019 is the 4th iteration ever organized by Penang Skills Development Center (PSDC). Since the first ever IMESS, we have always participate as part of the sponsor and exhibitor of the event. We believe that IMESS is a great platform for local industry to connect. Who knows what …
5 Minutes Introduction to EM Wave
In the previous article, we mentioned that James Maxwell unified the electric and magnetic fields by combining the four Maxwell’s equations into a single wave equation which predicts the existence of the electromagnetic (EM) wave. The discovery of EM wave is a major breakthrough in modern physics because it let us understand the phenomena of …
3 Quick Tips to Designing with EDS
What makes designing process enjoyable? Its when you do not need to perform many tedious tasks just to get something simple done. In EDS, we are always thinking on how to make the designing process as intuitive and easy as possible. In today's blog, here's 3 quick tips that you may not know on how …
5 Minutes History of Electricity
Thales of Miletus Ever wonder what's the history of electricity, which has become a daily necessity to modern man? To start, we have to look into the history of electromagnetism. The history of Electromagnetism can be categorized into two eras; classical and modern eras. This covers from the classical era of the fundamental laws of …
Transmission Line Filter Using Richard’s Transformation
Transmission Line (TL) In our previous article, we talked about the parasitic capacitance and inductance of circuits designed in lumped element. With majority of device and applications operating in high frequencies, especially with the introduction of 5G at millimeter wave, it is unfeasible to design filters using lumped elements. This is where transmission line type …
