Abstract
Provided is a phase array receiver. A phase array receiver according to an embodiment of the present invention includes a plurality of antennas, a plurality of low-noise amplifiers, a plurality of phase shifters, a plurality of transconductors, and a frequency mixer. A plurality of low-noise amplifiers amplify RF signals received from the plurality of antennas. The plurality of phase shifters adjusts the phase of the RF signals to generate a plurality of RF phase adjustment signals. The plurality of transconductors convert a plurality of RF phase adjustment signals into a plurality of RF current signals based on the gain control signal. The frequency mixer converts a sum of the plurality of RF current signals into a mixed current signal. According to the inventive concept, the linearity of the signal processing may be improved and the area for the implementation of the phase array receiver may be reduced.
