We see from your search that you're looking for information on the term "Cellular infrastructure",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release No compromise for low-cost ceramic filters from
Aspen Electronics, which we summarised at the time by saying "Ceramic filters cover the frequency band from 40MHz to 5GHz, making them particularly suitable for applications such as cellular infrastructure equipment and wireless LANs".
Several months prior to that,
we featured the news release Low noise amps are optimised for infrastructure from
Avago Technologies: "The MGA-631P8 and -632P8 are designed for easy integration into the receiver chain for GSM, CDMA2000, WCDMA and WiMAX basestations and repeaters".
In February 2007, we covered the news from Intersil
concerning its ISL12024/25
- take a look at Clock, calendar and alarm come together
which says: "Real-time clocks feature an integrated factory-set 64bit unique ID that is read-only and tamper-proof for increased security and reduced footprint and BOM cost".
Take a look also at the news release from Texas Instruments (April 2006-), Ready for the new world network,
as well as Fabless model paves way for fast growth from Wintegra,
and RO4230 high frequency circuit material from Rogers Corp.
