Maximizing battery life and data rate for 3G/4G mobile devices
In a decade the mobile phones went from simple handheld telephone to supercomputing
feature-full smartphone devices. This transformed the way we access and exchange
information in a ubiquitous way. But all the new features, radios and huge processing
power require always more space and more antennas on a small board. While antenna
size shrunk, larger bandwidth of operation has been requested (LTE, WiFi, etc.) ultimately
resulting in poor antenna performance. Antenna aperture tuning solutions are the
necessary toolbox for smartphone vendors to make small but efficient antennas.
Infineon antenna tuning solutions value
The antenna tuning devices based on Infineon’s RF CMOS switch technology are designed
for ultra-small size, high ruggedness in mismatch conditions, low parasitic and best
linearity. Improved antenna efficiency directly translates into better signal quality, fastest
data transmission and longer battery life. All devices offer generic GPIO interfaces for
smooth antenna control and system integration.
