Abstract
An integrated, multi-band radio frequency (RF) filter is capable of modifying a filter response thereof in response to control information. Switching elements within the filter can be changed between on and off conditions to modify the filter response. In one implementation, the integrated, multi-band filter is integrated on a front end module chip to be used within a multi-radio wireless device. In at least one embodiment, linearity enhancement circuitry is provided within a multi-band filter to improve linearity and reduce insertion loss.
