?Cellular Telephones?

An Electronicstalk guide

Start with the news release Gain blocks for cellular bands GSM, CDMA and UMTS from Avago Technologies, which we summarised at the time by saying "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.". Several months prior to that, we featured the news release AC/DC power supplies suit harsh environments from XP Power: "XP Power has unveiled the ECC100 series 100W single-output, baseplate-cooled AC/DC power supplies targeted at outdoor applications such as wireless communications, lighting and information displays.".

In December 2010, we covered the news from Taiyo Yuden - take a look at Chip filters optimise performance of mobile phones which says: "Taiyo Yuden's latest lines of chip filters are designed to optimise the performance, while minimising the size, of mobile phones. ".

Take a look also at the news release from Bulgin Components, Vandal-resistant switches enable access control, as well as RMS detector can be used in rugged environments from Linear Technology, and Low-noise amplifiers ideal for handheld devices from Maxim Integrated Products.
