?Digital Amplifier?

An Electronicstalk guide

Start with the news release Rakon TCXOs feature power management from Rakon, which we summarised at the time by saying "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. ". Several months prior to that, we featured the news release CMOS image sensor put inside digital film camera from Cypress Semiconductor: "Cypress Semiconductor's CMOS image sensor has been designed into the 35mm Alexa digital motion-picture camera from ARRI, used to produce films including 3D movies and commercial shoots.".

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 Magna-Power Electronics, High slew-rate option for power supplies, as well as VGA for wireless infrastructure transceivers from Maxim Integrated Products, and Sensor IC withstands harsh automotive environments from Allegro Microsystems.
