RF platform brings three radios together
Texas Instruments has developed the industry's first solution that integrates mobile WLAN (mWLAN), Bluetooth and FM stereo audio all in a space-saving platform for mobile phones.
In addition, they will discuss elements of electromagnetic compatibility (EMC) testing, filter component characteristics and proper PCB layout.
Engineers are invited to register for the one-hour session via the TI website.
Webcast panellists will provide an overview of Class-D audio power amplifiers that use switched output devices to produce power with high efficiency.
There are a variety of ways to control the switching patterns.
One technique that will be highlighted is Class-BD modulation, which permits operation without an output filter in many applications, thereby reducing cost and complexity.
In addition, panellists will discuss benefits of Class-D amplifiers and compare efficiency, heat generation and battery life with Class-AB amplifiers.
Knowing the difference between the amplifiers is key to successful designs for handheld devices.
During the lab segments, Klein and Crump will demonstrate how to achieve EMC through a better understanding of electromagnetic interference (EMI) filter component characteristics and PCB layout principles.
They will use a working EMI chamber to illustrate EMI testing.
