We see from your search that you're looking for information on the term "UMTS",
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 Power amps cut handset transmission drain from
Avago Technologies, which we summarised at the time by saying "Active bypass mode in power amplifiers provides tremendous benefit to extending handset battery life in today's CDMA and UMTS/GSM networks".
The same day,
we featured the news release Programmable transceiver covers a broad band from
BitWave Semiconductor: "Fully software configurable across all channels in the frequency bands between 700MHz and 3.8GHz".
In February 2008, we covered the news from Qualcomm
concerning its MDM9xxx-series LTE device chipsets
- take a look at Chipsets upgrade for the long term
which says: "Multimode Mobile Data Modem chipsets deliver significant flexibility to the industry by supporting LTE, as well as other 3GPP and 3GPP2 standards".
Take a look also at the news release from Spirent Communications, Location test system adds new options,
as well as WiFi accessory offers an easy upgrade from Telit Wireless Solutions,
and Reference designs cover Long Term Evolution from picoChip Designs.
