摘要: An image rejection and pseudo-image enhancement mixer wherein diodes are coupled to a signal source through power divider without resistor, local oscillator directional filters outputs quadrature coupler. A 90° phase shifter between one diode the resistor provides for cancellation of signal, while is terminated at output port desired obtained another
