Abstract: In certain aspects, a method includes receiving a first intermediate frequency (IF) signal and a second IF signal via a common input, upconverting the first IF signal into a first radio frequency (RF) signal, transmitting the first RF signal via a first antenna array, upconverting the second IF signal into a second RF signal, and transmitting the second RF signal via a second antenna array. In a first transit mode, the first RF signal is in a first frequency band and the second RF signal is in a second frequency band, and, in a second transmit mode, the first RF signal and the second RF signal are both in the first frequency band.
