| Popis: | This brief describes an integrated system performing automatic matching of antenna impedance, suitable for applications within the 433 MHz ISM band. The detected impedance can be matched to ${50}~{\Omega }$ . Consequently the input S-parameter of the antenna can be reduced far below −20 dB. This system has been implemented on a 130-nm CMOS SOI technology process with an integrated ${\pi }$ matching network. The design of the chip is focused for measure and correct impedance of the antenna. Both simulation and measured results are presented to validate the methodology. |
