‘Operational Amplifier’
An Electronicstalk guide
Start with the news release
Signal generator achieves optimum output power from
Rohde and Schwarz, which we summarised at the time by saying "Equipped with new options, the RandS SMF100A from Rohde and Schwarz now achieves optimum values in output power and single sideband phase noise. ".
Several months prior to that,
we featured the news release Avago designs duplexer for UMTS Band 2 handsets from
Avago Technologies: "Avago Technologies has announced a miniature PCS duplexer that has been specifically designed for use in UMTS Band 2 handsets. ".
In July 2009, we covered the news from Fairchild Semiconductor
- take a look at Fan5902 extends 3G handsets' talk time by 40mins
which says: "Fairchild Semiconductor has introduced the Fan5902, a tiny power-management solution for designers of 3G handsets and wireless datacards.".
Take a look also at the news release from Atmel Corporation, AT32UC3L MCU features low-power technology,
as well as Maxim launches MAX19996A down-converting mixer from Maxim Integrated Products,
and Gain block also works as a driver amplifier MMIC from Avago Technologies.
