We see from your search that you're looking for information on the term "CDMA", 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 Chipsets enable connected mobile entertainment from Qualcomm: "Combined support for wireless connectivity; high-accuracy multimode GPS positioning; a high-performance applications processor; support for broadcast mobile TV; and rich multimedia".
In February 2008, we covered the news from TDC (Telecom Design Communications) concerning its Antenova M10214 GPS receiver - take a look at GPS receiver combines RF and antenna modules which says: "TDC's Antenova M10214 can track up to 20 satellites simultaneously and maintain a fix at speeds of more than 500m/s".
Take a look also at the news release from Qualcomm, Chipsets upgrade for the long term, as well as WiFi accessory offers an easy upgrade from Telit Wireless Solutions, and Mobile duplexer cuts size and losses from Avago Technologies.
