Bluetooth Low Energy Device
Wireless communications has become a staple in modern electronics, and Bluetooth is one of the most ubiquitous forms of wireless technology. There are so many different types of BLE devices, but all of them will be concerned with antenna type, gain, transmission power, tuning components, and radiation pattern.
WIRELESS POWER SYSTEM
Wireless Power is becoming more prevalent every day, ranging from milliwatts to kilowatts of power. Surprisingly high efficiencies can be achieved in wireless power, and this is especially important as power goes beyond 1KW. Coil geometry, coupling factor, turns ratio, coil tuning, resistance, and switching topology are all key aspects to wireless power system design.
PRO AUDIO AMPLIFIER
Pro Audio is a $22 billion dollar industry, rife with competition. Dozens of design decisions go into optimizing the sound for a particular amplifier including speaker size, cabinet design, port design, preamp controls, EQ, and power amplifier.
DEVICE NETWORKING
There is more need for device networking now than ever before. In the increasing world of IoT, the market demands fast, reliable communication between devices. When designing a communication network, throughput, latency, speed, bus length, bus traffic, network protocol, and system-level architecture all need to be considered.
OFF-LINE SMPS POWER SUPPLY DESIGN
Though switching power supplies have been around for decades, they have become more sophisticated, lighter, smaller, and more powerful. Switching topology, transformer design, feedback control, and especially radiated and conducted emissions are all important factors in SMPS design.
