Multi-band interference optimization

摘要

RF communications circuitry, which includes a first RF filter structure and control circuitry, is disclosed. The first RF filter structure includes a pair of weakly coupled resonators and a first tunable RF filter. The control circuitry provides a first filter control signal. The first tunable RF filter receives and filters an upstream RF signal to provide a first filtered RF signal, such that a center frequency of the first tunable RF filter is based on the first filter control signal.

1. An apparatus comprising:
a first RF filter structure comprising a pair of weakly coupled resonators and configured to provide a first tunable RF filter, which is configured to receive and filter an upstream RF signal to provide a first filtered RF signal, such that a center frequency of the first tunable RF filter is based on a first filter control signal, wherein the first tunable RF filter is further configured to be a reconfigurable tunable RF filter, such that a shape of a transfer function of the first tunable RF filter is reconfigurable, and a configuration of the first tunable RF filter is based on a first filter reconfiguration signal; and control circuitry configured to provide the first filter control signal.
