Abstract
Methods, systems, and apparatuses are described for generating a phase-shifted signal in a transmit path and a receive path of a transceiver. When transmitting, a quadrature hybrid in the transmit path generates at least one in-phase signal and at least one quadrature signal based on a modulated signal. Phase shifters generate phase-shifted versions of the modulated signal based on a combination of these signals. When receiving, antennas receive a modulated signal and provide the modulated signal to phase shifters in the receive path. Each phase shifter modifies its received modulated signal. A matching network combines each of the modified modulated signals and provides at least one combined modulated signal to a quadrature hybrid. The quadrature hybrid generates a phase-shifted version of the modulated signal based on the at least one combined signal.
