1. A filter bank module comprising:
a substrate;
an antenna port terminal; and
a filter bank die fixed to the substrate, the filter bank die comprising:
a first acoustic wave (AW) filter having a first antenna terminal coupled to the antenna port terminal and a first filter terminal;
a second AW filter having a second filter terminal, and a second antenna terminal coupled to the first antenna terminal to effectively diplex signals that pass through the first AW filter and the second AW filter; and
a double-throw switch having a first throw terminal coupled to the first filter terminal and a second throw terminal coupled to the second filter terminal, a transmit pole terminal, and a receive pole terminal, wherein an insertion loss between either of the transmit pole terminal or the receive pole terminal and the antenna port terminal minus an insertion loss of either the first AW filter or the second AW filter is no greater than 1.2 decibels, and wherein a real estate area of the filter bank module is no greater than 4 square millimeters.
