摘要： Provided is a switching circuit for a millimeter waveband control circuit. The switching circuit for a millimeter waveband control circuit includes a switching cell disposed on a signal port path to match an interested frequency and including at least one transistor coupled vertically to an input/output transmission line and a plurality of ground via holes disposed symmetrically in an upper portion and a lower portion of the input/output transmission line; capacitors for stabilizing a bias of the switching cell; and bias pads coupled in parallel to the capacitor to control the switching cell. Therefore, the switching circuit may be useful to improve its isolation by simplifying its design and layout through the use of symmetrical structure of optimized switching cells without the separate use of different switch elements, and also to reduce its manufacturing cost through the improved yield of the manufacturing process and the enhanced integration since it is possible to reduce a chip size of an integrated circuit in addition to its low insertion loss.

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： Provided is a microwave module having a converter for improving transmission characteristics in a millimeter-wave band. When a microstrip transmission line and a conductor-backed coplanar waveguide (CBCPW) transmission line are connected by wire bonding, a change in impedance caused by wire bonding and an abrupt change in electric field components between the two transmission lines are reduced by the converter. Therefore, insertion loss and return loss are reduced, and transmission characteristics in a millimeter-wave band are improved.
