Abstract
A programmable acoustic filter circuit is provided. Herein, the programmable acoustic filter circuit can be dynamically controlled to toggle between two different passbands, such as different unlicensed national information infrastructure (UNII) bands. The programmable acoustic filter circuit includes an insertion element, a main filter, and a notch circuit. The insertion element is coupled in series with the main filter with very low insertion loss. Specifically, the notch circuit can be dynamically decoupled from the insertion element to thereby cause the main filter to pass a radio frequency (RF) signal in a main passband or be coupled to the insertion element to thereby cause the main filter to pass the RF signal in an alternative passband different from the main passband. As a result, it is possible to flexibly configure the programmable acoustic filter circuit to provide adequate out-of-band rejection with lowest possible insertion loss in various coexisting and concurrent operations.
