MULTIPLEXER WITH ACOUSTIC ASSISTED TRAP CIRCUIT

Abstract: aspects of this disclosure relate to a multiplexer with an acoustic assisted trap circuit. the multiplexer includes an acoustic wave filter with an acoustic wave resonator and an impedance network that together provide a trap for a harmonic associated with another acoustic wave filter of the multiplexer. the acoustic wave filter can have an edge of a passband that is farther from the harmonic than other acoustic filters of the multiplexer.
