A 1.7-6.4 GHz fourth-order RF filter with 1-40% fractional bandwidth in 22-nm FDSOI

The rise of 5G technology leads to a boom in the demand for widely available wireless connectivity while requiring telecommunication networks to improve spectral efficiency and deploy dynamic spectrum sharing (DSS) and carrier aggregation (CA). This imposes more stringent intermodulation test scenarios and blocking requirements on RF transceivers. In addition, they are required to be programmable for various bandwidth and gain configurations over a broad frequency range.
