초록정보

A phase shifter is the Microwave control component employed to realize the phase shift function in an electrically scanned array system. Satellite systems will utilize phased array antennas and they require tens of thousands of phase shifters per satellite. In this thesis, the design of a K-band monolithic integrated circuit ( MMIC ) phase shifter utilizing TriQuint 0.25-㎛ pseudomorphic high electron mobility transistor ( pHEMT ) technology is presented. A new 180˚ phase bit circuit has been designed and reduced to practice. The 90˚ ,45˚ and 22.5˚ phase bit circuit employ an embedded type phase shifter using sprial inductor. The circuit size is 2.4mm×0.9mm. The EM simulation is utilized to analyze the error between simulation results and measured results. All transmission lines and connecting vias are EM simulated. In appendix, a K-band balanced frequency doubler using InGaP/GaAs HBTs is presented. To obtain balanced signal , a differential amplifier with a base-collector feedback resistor is utilized. The push-pull doubler operates in a near class B region for good efficiency. This circuit has a conversion gain of 6dB over the output frequencies from 14GHz to 24GHz. The fundamental frequency suppression is better than -17dBc.The circuit size is 0.6×$0.7mm^2$.
