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.

Claim (Index 10):
A phase array receiver comprising:\n a plurality of antennas configured to receive RF signals; a plurality of phase shifters configured to determine a reception direction of the RF signals of the plurality of antennas; a plurality of transconductors configured to convert a plurality of voltage signals generated based on the RF signals into a plurality of RF current signals and output the plurality of RF current signals to a summation node; a reception controller configured to provide the plurality of transconductors with a gain control signal for determining a current conversion ratio of each of the plurality of transconductors; a frequency mixer configured to receive a sum of the plurality of RF current signals from the summation node and generate a mixed current signal having a lower output frequency band than the sum of the plurality of RF current signals; and a transimpedance amplifier configured to convert the mixed current signal into a mixed voltage signal
