Methods for antenna switch modules are disclosed. In certain implementations, a method of making an antenna switch module is provided. The method includes providing a package substrate implemented to receive one or more electrical components, attaching a silicon on insulator (SOI) die to the package substrate, and providing an integrated filter. The SOI die includes a capacitor and a switch coupled to a plurality of radio frequency (RF) signal paths. The integrated filter filters an RF signal received on a first RF signal path of the plurality of RF signal paths, and includes the capacitor of the SOI die and an inductor.
