The multi-band RF circuit includes multiple antenna ports coupled to multiple antennas and an antenna swapping circuit coupled to the multiple antenna ports. Control circuitry in the multi-band RF circuit controls the antenna swapping circuit to selectively couple various transmit and/or receive filters with any one or more of the multiple antenna ports to support uplink carrier aggregation (ULCA) and/or multiple-input multiple-output (MIMO) operations with a minimum number of transmit and receive filters. Transmit filters of adjacent RF bands are physically separated, but disposed in proximity, in the multi-band RF circuit to help reduce intermodulation products between the adjacent RF bands during the ULCA operation. As a result, it is possible to improve RF performance of ULCA and MIMO operations, without increasing complexity, cost, and footprint of the multi-band RF circuit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Multi-band radio frequency circuit","description":"Embodiments of the disclosure include a multi-band radio frequency (RF) circuit.
