A Highly Integrated X-band Frequency Quadrupler MMIC using 3D-MMIC Technology

摘要

A highly integrated X-band frequency quadrupler MMIC using three-dimensional MMIC (3D-MMIC) technology is presented. It consists of four amplifiers, two doublers, and a 2-band elimination filter. These seven circuits are integrated on only a 2.25 mm times 1.05 mm chip. The third and fifth harmonic components, which are spurious components nearest to the desired component, are well suppressed. The desired/undesired ratio is about 40 dB. The MMIC supplies +5 dBm of the fourth harmonic component at input power as low as -10 dBm. The power dissipation of the MMIC is only 160 mW.
