High resolution, high performance converters and radio frequency (RF) systems require good power supply noise filtering and high frequency crosstalk reduction between analog and digital domains. An effective method for filtering high frequency power supply noise and cleanly sharing similar supply rails is the use of ferrite beads. A ferrite bead is a passive device that filters high frequency noise energy over a broad frequency range, where it then becomes resistive and dissipates noise energy in the form of heat. This application note presents and discusses Analog Devices’ products that demonstrate the effects of ferrite beads as output filters.
Microsemi Corporation will feature 13 new products from its radio frequency (RF), microwave and millimeter wave integrated circuits (ICs), modules, monolithic microwave integrated circuits (MMICs) and subsystem portfolio at the 2015 IEEE MTT-S International Microwave Symposium (IMS2015) and Exhibition at the Phoenix Convention Center in Phoenix, Arizona May 17-22, 2015.
