In The basics of 4-20mA current loop transmitters, I discussed the basics of 4-20 mA transmitters, a popular communication method to and from field elements in factory automation and other industrial ...
There are essentially four different types of pressure measurement transmitters. Absolute pressure transmitters measure against a vacuum, meaning that if no pressure is applied, the reading would ...
Recent advances in high-speed data converters now digitize or generate signals directly at radio frequencies up to several gigahertz, replacing traditional radio-frequency (RF) components like mixers, ...
For Nautel’s head of customer service, John Wilton, the “aging out” of broadcast engineers is a rising concern. Why? The lack of RF knowledge could put Radio at risk in the coming years. That has led ...
David Houze is Ecreso product manager, leading development of the FM transmitter range in collaboration with WorldCast Systems’ R&D team. He is also an application engineer supporting WorldCast’s APT, ...
The author is account manager, radio transmitters for Rohde & Schwarz, handling Canada and the United States. Liquid cooling for transmitters seems a bit exotic to many radio engineers, but truthfully ...
The proposed CORDIC-less digital polar transmitter demonstrates superior power added efficiency (PAE) and system efficiency (SE) for similar modulation signals. It also supports wider bandwidths, ...
