  • Vector modulator
    Patent number: 8588337
    Abstract: Disclosed is a vector modulator. The vector modulator can control the amplitude and phase of an input signal, by not using amplitude variable attenuators but using phase shifters. Further, the vector modulator has a simple configuration and enables an input signal to be exactly modulated. Furthermore, the vector modulator can modulate the phase of an input signal throughout all areas in the polar coordinate system.
    Type: Grant
