Abstract
The detector comprises a first distributor for distributing a signal wave, a 45 degree shifter for shifting a local oscillation, a first even harmonic mixer and a second even harmonic mixer for generating a mixed wave between a double frequency wave of said local oscillation wave and said signal wave. The present invention can be used for increasing the accuracy and downsizing of quadrature mixer used in a receiving transmitting apparatus of a wireless communication system.
