1. A radio frequency front end system comprising:
a first transmit and receive module including at least one power amplifier, at least one low-noise amplifier, and one or more filters, the first transmit and receive module configured to provide multi-input multi-output (MIMO) receive operations for a first plurality of mid bands and a first plurality of high bands, the first transmit and receive module further configured to provide transmit operations for the first plurality of mid bands, the first transmit and receive module including a first node; and
a second transmit and receive module including at least one power amplifier, at least one low-noise amplifier, and one or more filters, the second transmit and receive module configured to provide transmit and receive operations for a second plurality of mid bands and a second plurality of high bands, the second transmit and receive module being a power amplifier integrated duplexer (PAiD) module, the second transmit and receive module including a second node, the first transmit and receive module and the second transmit and receive module coupled by a signal path at the first node and the second node, respectively, the second transmit and receive module coupled to at least one antenna, the second transmit and receive module configured to provide receive signals from the at least one antenna to the first transmit and receive module through the second node, the signal path, and the first node.
