Abstract

In this letter, an initial verification results of a bandwidth tunable power amplifier in Ku-band designed by the hybrid semiconductor integrated circuit (HySIC) concept is reported. A GaAs monolithic microwave integrated circuit (MMIC) and a Si radio frequency integrated circuit (RFIC) were utilized as the HySIC configuration in the circuit design. For the purpose of initial confirmation of this design validity, the GaAs and Si chips were fabricated and packaged onto the copper tungsten plate with gold plating. As measured results, the lower cut-off frequency was changed from 9.8GHz to 11.9GHz, resulting in the bandwidth tunability in Ku-band.
