Infineon Technologies Antenna Tuner RF Switch ICs improve antenna radiation efficiency while promoting higher data rates, longer battery life, and improved signal quality. Antenna tuning can be performed in two ways: aperture tuning shifts the natural resonance of an antenna to the necessary operating frequency band, while impedance tuning optimizes signal transmission to the antenna by compensating frequency and environmental effects. The Infineon Technologies Antenna Tuner RF Switch ICs address antenna design challenges while enabling maximum power transfer, delivering the desired antenna efficiency.
