Antenna Control Solutions
The challenges associated with 3G/4G smartphone antenna design have grown remarkably
in recent years. Consumer demands for sleek, thin handsets with big screens, longer
battery life, and higher data rates, along with a growing and increasingly crowded
frequency spectrum, have brought handset antenna performance and size into acute
The antenna has long been considered and designed as a passive device, which in
its simplest form is composed of little more than a carefully constructed pattern
of conductive material. In light of recent challenges, antenna designers have increasingly
turned to integrating components like switches and programmable capacitors or programmable
arrays of capacitors (PACs) to actively tune performance and facilitate smaller
RFMD is at the forefront of this trend towards smaller, active-tuning devices through
heavy investment in the development of high-performance 3G/4G antenna control solutions
(ACS). These devices consist of switches and PACs designed to fit the specific needs
of this important application. RFMD’s portfolio of 3G/4G ACS products will continue
to grow to meet increasing customer adoption rates and accelerating design wins
at leading OEMs.
RFMD 3G/4G antenna control solutions help customers solve the increasingly complex
challenges in multimode, multi-band front ends. By optimizing antenna performance
across modes and bands, RFMD's antenna control solutions improve call quality, extend
battery life and enhance the smartphone consumer experience.
