Abstract
A multi-band radio frequency (RF) front-end circuit is provided. The multi-band RF front-circuit includes multiple RF circuits configured to amplify RF signals received and/or to be transmitted in multiple RF bands and/or polarizations via an antenna circuit. The antenna circuit includes multiple antenna tap points each coupled to a respective one of the RF circuits. Since each of the RF circuits has a respective impedance that can vary based on the RF bands, the antenna tap points are so positioned on the antenna circuit to each present a respective drive impedance that matches the respective impedance of a coupled RF circuit. Further, the antenna tap points are also positioned on the antenna circuit to cause desired RF isolations between the RF bands and/or the polarizations. Consequently, the multi-band RF front-end circuit can achieve optimal RF performance across a wide range of RF bands with reduced footprint and insertion losses.
