), Wi-Fi systems, small telecommunication cells and modules for those. Such filters are made from a network of resonators (either in half-ladder, full-ladder, lattice, a combination of lattice and ladder or stacked topologies) and are designed to remove unwanted frequencies from being transmitted in such devices, while allowing other specific frequencies to be received and transmitted. FBAR filters can also be found in duplexers.
Filters used in Wi-Fi systems, small telecommunication cells, and modules are designed to remove unwanted frequencies from transmissions. They achieve this by using a network of resonators (in various topologies like half-ladder, full-ladder, lattice, or combinations thereof) that allow specific frequencies to be received and transmitted while blocking others. FBAR filters can also be found in duplexers.
