A surface acoustic wave filter includes an acoustic track bounded by
reflectors, at least a first input transducer and at least a second input
transducer acoustically coupled to the acoustic track that are connected
in parallel and connected to an asymmetric input port, at least two first
output transducers acoustically coupled to the acoustic track that are
connected in parallel and connected, to a first terminal of a symmetric
output port and at least two second output transducers acoustically
coupled to the acoustic track that are connected in parallel and
connected to a second terminal of a symmetric output port. Each first
output transducer in the acoustic track and corresponding second output
transducers are side-by-side and are electrically connected in series via
a first bus bar.
