Filter with multiple outputs or inputs to implement multiple filter frequency responses

An apparatus, comprising:

• a first low noise amplifier (LNA);
• a first filter comprising a first filter input, a second filter input, a filter output, and a plurality of micro-acoustic resonators, the first filter coupled between an antenna and the first LNA, the plurality of micro-acoustic resonators coupled between the first filter input to the first filter and the filter output of the first filter, a sub-set of one or more of the plurality of micro-acoustic resonators coupled between the second filter input to the first filter and the filter output of the first filter, the second filter input to the first filter bypassing a portion of less than all of the plurality of micro-acoustic resonators, wherein the first filter is configured to:
• apply a first filter frequency response to a first signal propagating from the first filter input to the filter output;
• and
• apply a second filter frequency response to a second signal propagating from the second filter input to the filter output;
• a first switch coupled between the antenna and the first filter input;
• and
• a second switch coupled between the antenna and the second filter input.

An apparatus, comprising:

• at least one low noise amplifier (LNA);
• and
• a filter comprising a first input port, a second input port, an output port, and a plurality of micro-acoustic resonators, the filter coupled between an antenna and the at least one LNA, the plurality of micro-acoustic resonators coupled between the first input port and the output port of the filter, a sub-set of one or more of the plurality of micro-acoustic resonators coupled between the output port and the second input port of the filter, the second input port bypassing a portion of less than all of the plurality of micro-acoustic resonators, wherein the filter is configured to:
• apply a first filter frequency response to a first signal propagating from the first input port to the output port of the filter;
• and
• apply a second filter frequency response to a second signal propagating from the first input port to the second input port of the filter or from the second input port to the output port of the filter.
