Filtering architectures and methods for wireless applications. In some embodiments, a wireless architecture can include a pre-amplifier filter configured to filter a signal, and an amplifier assembly configured to amplify the filtered signal. The wireless architecture can further include a filter circuit configured to provide selective filtering of the amplified signal based at least in part on a rejection level of the pre-amplifier filter and a gain of the amplifier assembly. In some embodiments, such a wireless architecture can be implemented in a packaged module or a wireless device.
