Matching circuit, wiring board, and transmitter, receiver, transceiver, and radar apparatus that have the matching circuit

摘要: There are provided a matching circuit which is less prone to impedance mismatch even with variations in pattern dimension, and wiring board, also transmitter, receiver, transceiver, radar apparatus that succeed offering stable characteristics the installation of circuit. Characteristic first transmission line including connection portion varied between reflection source stub bonding wire serving as load. Impedance variation achieved by varying distance from back conductor layer coupled thereto respect an inner them.
