Abstract
A radio frequency (RF) system includes an RF integrated circuit (IC) die. The RF IC die includes a first transmit circuit, a second transmit circuit, a first receive circuit, a second receive circuit, and a control circuit coupled to the first transmit circuit, the second transmit circuit, the first receive circuit, and the second receive circuit. The RF system further includes a first antenna coupled to the first transmit circuit and the first receive circuit using a first coupling structure. The control circuit is configured to activate the first transmit circuit and deactivate the first receive circuit during a first operation mode. The RF system further includes a second antenna coupled to the second transmit circuit and the second receive circuit using a second coupling structure. The control circuit is configured to activate the second transmit circuit and deactivate the second receive circuit during a second operation mode.
