We see from your search that you're looking for information on the term "Cellular 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 Convertor copes with green energy standards from
Advanced Analogic Technologies, which we summarised at the time by saying "Synchronous step-down DC/DC convertor offers power savings in a variety of industrial applications, especially those using backplanes".
A few weeks before,
we featured the news release PCB laminates answer RF demands from
Rogers Corp: "Laminates provide the controlled relative permittivity, low loss and passive intermodulation response required by the wireless infrastructure market".
In May 2007, we covered the news from Linear Technology Corp
concerning its LT5571
- take a look at Modulator boasts high dynamic range
which says: "High-performance quadrature modulator is optimised for 850 to 965MHz GSM, CDMA2000, ISM and RFID modulator applications".
Take a look also at the news release from SynQor Europe, Bricks to power cellular basestations,
as well as Oscillator cuts the cost of comms kit from Bliley Technologies,
and Distribution agreement spreads down under from Nu Horizons Electronics Corp.
