3G CDMA / EVDO

TriQuint's CDMA product portfolio, including the highly integrated TRITIUM™ family, offers customers excellent battery life and extended operating time, enabling high performance in the smallest form factors.

Our power amplifier modules include a three-gain state gallium arsenide (GaAs) die that operates in low, medium and high power modes to maximize talk time over the entire range of operating conditions. Our BAW filters are specifically designed to meet the high-performance expectations of insertion loss and rejection for CDMA / WCDMA / LTE diversity receive systems.

Key Benefits

  • High efficiency
  • High linearity

Where are we with 3G and the shift to new standards for 4G networks?

Major U.S. wireless networks are using 3G specifications, providing users with a noticeable improvement in data speed. 3G allows simultaneous use of voice and data transfers. The speed of a smartphone browser and the ability to send and receive pictures and larger files are significant 3G enhancements.

While 4G offers even more capability, there are different approaches to 4G standards. Whenever there are new generations of wireless standards, differing innovations are developed and tend to find their own audiences over time.

One major 4G standard is Long Term Evolution (LTE). LTE commitments are the logical extension for organizations whose current systems are UMTS / 3GPP based. LTE is favored by organizations that hold paired frequency spectrum allocations.

Regardless of which standards prevail, TriQuint will support new generations of systems to assist all developers as they work towards continuous improvement. We do this while looking ahead of the current trends in the evolution of wireless.

What exactly are the improvements that make each new generation?

Generation changes in wireless communications generally have to do with both the data rate and architecture of the system infrastructure. It is safe to say that each new generation enables higher data rates, lower latency and new applications relative to the previous one.

One major change is that 4G systems use a packet infrastructure rather than traditional telephone architecture. Since 4G is relatively new, it will still take time for the full extension of the improvements to present themselves.

What is 4G and where does it fit in the development of cellular communication standards?

4G refers to the Fourth Generation of cellular wireless standards.

The First Generation (1G) of cellular wireless supported analog mobile phones. Next came Second Generation (2G) digital service, which offered a significant upgrade in capabilities. The Third Generation (3G) supports multimedia, spread-spectrum transmission with larger volumes of data transfer and improved speeds. It enables numerous applications including e-mail and web browsing.

Fourth Generation (4G) takes the capabilities of wireless a step further. 4G increases bandwidth and modulation complexity and adds spatially multiplexed data streams (MIMO). This in turn increases the data rates and enables exciting new services and applications. For example, the key 2G application was voice. 3G brought data services to the market, enabling e-mail and web browsing. 4G applications are still being defined but may include things like streaming video.
