Antenna aperture tuning solutions

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.
