A direct conversion receiver is disclosed wherein a received RF signal is mixed in a mixer with a local oscillation signal having a frequency the same as a desired central frequency, and is down-converted to a base band signal. The receiver comprises a divider for dividing the received RF signal; an adder provided at a received RF signal input side of the mixer; a phase shifter provided before the input of the mixer, for shifting a phase of the divided signal of the received RF signal; and a gain adjustable amplifier provided after the divider, and before or after the phase shifter, for amplifying the divided signal to supply the phase-shifted and amplified signal to the adder. Accordingly a DC offset due to the direct conversion can be removed and an adverse effect due to transient response when the DC offset changes can be prevented.
