EDGE—Enhanced Data Rates for Global Evolution

This 2.5G technology is part of the evolution of the GSM standard and enables

data transmission rates in excess of 100 Kbps. Designers and manufacturers of

EDGE-enabled handsets face the ongoing challenges of improving time to market (TTM)

and lowering the cost of implementation (COI), while providing the benefits of feature rich

devices. As with most emerging standards, the relatively small number of manufacturers

as compared to the previous generation is indicative of the complexity of the devices.

While optimizing for stringent, 8-PSK requirements, the EDGE market demands that

GMSK efficiency remains on par with that seen in GPRS handsets. Additionally, 8PSK

efficiency is quickly becoming a priority parameter as we see applications that require

higher data rates becoming more prevalent and more test and calibration steps are

being added through development and production. Last but not least, the lack of EDGE

market maturity has also led to a variety of transmit architectural approaches (linear and

large signal polar modulation).

These demands are brought about by the need to support both EDGE only and 3G multi-

mode handsets. Even when the transmit architecture is the same, the RF front-end

requirements are different, as well as output power and transmit switch performance,

to name two prominent parameters. Furthermore, top original equipment manufacturers

(OEMs) and network operators are raising the performance bar by placing demands of

total radiated power (TRP) and specific absorption rate (SAR) compliance simultaneously

with demands for maintaining or improving talk time.

This evolving market is constantly bringing forward new, complex challenges in the

EDGE front-end space. These are the challenges that require leading-edge technologies

and techniques in order to deliver the types of quality front-end solutions our customers

have come to expect from RFMD.

The requirements and priorities of OEMs and original design manufacturers (ODMs)

in this demanding market vary depending on experience, resources and their chosen

vectors of differentiation. RFMD focuses on addressing the variety of customer and

carrier priorities by offering a segmented portfolio of GSM/GPRS front-end products.
