We see from your search that you're looking for information on the term "Wireless basestations",
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".
The day before,
we featured the news release Direct digital synthesiser is made for handhelds from
Analog Devices: "The AD9913 is the first DDS device to deliver a 250MHz clock rate while consuming as little as 50mW of power".
In December 2007, we covered the news from Micrel
concerning its SY89228-231 divider product family
- take a look at Clock dividers take odd approach to stability
which says: "Divide by three and divide by five clock dividers are the only clock dividers that divide odd numbers and provide 50% duty cycle".
Take a look also at the news release from austriamicrosystems, LDOs are optimised for noise performance,
as well as Equalisers extend reach for PCBs and HDMI from National Semiconductor,
and Crosspoint switches run up to 4.25Gbit/s from Texas Instruments (April 2006-).
