    摘要: Provided is a high-isolation switching device for a millimeter-wave band control circuit. By optimizing a cell structure to improve the isolation of an off-state without deteriorating the insertion loss of an on-state, it is possible to implement a high-isolation switching device useful in the design and manufacture of a millimeter-wave band control circuit such as a phase shifter or digital attenuator using switching characteristics. In addition, when a switch microwave monolithic integrated circuit (MMIC) is designed to use the switching device, it is not necessary to use a multi-stage shunt field effect transistor (FET) to improve isolation, nor to dispose an additional λ/4 transformer transmission line, inductor or capacitor near the switching device. Thus, chip size can be reduced, degree of integration can be enhanced, and manufacturing yield can be increased. Consequently, it is possible to reduce manufacturing cost.

    摘要: An active quadrature signal generator produces poly-phase quadrature signals necessary in high frequency transmit and receive elements of a communication system. The quadrature signals are produced using the phase difference between a load representing a low-pass filter characteristic and a load representing a high-pass filter characteristic and the quadrature signal is then used in the differential structure to produce amplified signal having 4 quadrature phases. The device can reduce a loss characteristic of the signal and additional power consumption for compensating for it in a common poly-phase quadrature filter having only conventional resistors and capacitor.
