Multi-band radio frequency circuit

A multi-band radio frequency (RF) circuit comprising:

• antenna swapping circuitry coupled to at least one first antenna port coupled to at least one first antenna, at least one second antenna port coupled to at least one second antenna, at least one third antenna port coupled to at least one third antenna, and at least one fourth antenna port coupled to at least one fourth antenna, wherein each of the at least one first antenna, the at least one second antenna, the at least one third antenna, and the at least one fourth antenna is configured to transmit an RF uplink signal and receive an RF downlink signal in a first RF band having a first frequency spectrum, a second RF band having a second frequency spectrum higher than the first frequency spectrum, a third RF band having a third frequency spectrum higher than the second frequency spectrum, and a fourth RF band having a fourth frequency spectrum higher than the third frequency spectrum;
• and
• control circuitry coupled to the antenna swapping circuitry and configured to:
• control the antenna swapping circuitry to select one or more of the at least one first antenna port and the at least one second antenna port to receive the RF downlink signal in the second RF band;
• and
• control the antenna swapping circuitry to select one or more of the at least one third antenna port and the at least one fourth antenna port to transmit the RF uplink signal and receive the RF downlink signal in the third RF band and the fourth RF band.
