1. A radio frequency front-end system with filter reuse, the radio frequency front-end system comprising:
an antenna switch;
a filter coupled to an antenna port through the antenna switch;
a filter reuse switch;
a power amplifier having an output coupled to the filter through the filter reuse switch; and
a low noise amplifier having an input coupled to the filter through the filter reuse switch, the low noise amplifier, the filter reuse switch, the filter, and the antenna switch are implemented on a receive module, and the power amplifier is implemented on a power amplifier module.
