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.
