The first fully monolithic X-band twin-dipole antenna mixer consisting of a uni-planar twin-dipole antenna and a GaAs MESFET single gate mixer on the same GaAs substrate fabricated by monolithic microwave integrated circuit technology (MMIC) is reported. The total chip size is 5×5 mm 2. This circuit received an RF signal of 10 GHz and down-converted it to an IF signal of 1 GHz with a worse case conversion loss of 22 dB, defined as the ratio of output IF power dissipated in a 50 load to the RF available power received by the twin-dipole antenna. The experimental results demonstrate that this topology has potential applications in future low-cost millimeter-wave receivers for smart munitions seekers and automotive-collision-avoidance radars.
