An Electronicstalk guide

Start with the news release Linear introduces H-grade switching regulator from Linear Technology, which we summarised at the time by saying "Linear Technology has announced a H-grade step-down switching regulator for load dump and cold-crank conditions commonly found in automotive applications as well as 24V industrial supplies.". Several months prior to that, we featured the news release Rakon TCXOs feature power management from Rakon: "Rakon has developed a range of digitally controlled temperature controlled crystal oscillator that can maximise battery life and minimise the electronic signature of military equipment. ".

In December 2010, we covered the news from Avago Technologies - take a look at Gain blocks for cellular bands GSM, CDMA and UMTS which says: "Avago Technologies has expanded its high-performance power amplifier range with the MGA-31589 and MGA-31689 0.5-watt gain blocks, suitable for cellular infrastructure applications.".

Take a look also at the news release from Rogers, Rugged flame-retardent laminates for military PCBs, as well as VGA for wireless infrastructure transceivers from Maxim Integrated Products, and Sensor IC withstands harsh automotive environments from Allegro Microsystems.
