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

摘要： An amplitude modulator in which modulator characteristics can be tuned is provided. In an amplitude modulator, between two high frequency transmission lines for transmitting high frequency signals, is provided a PIN diode which is a high frequency modulating element that modulates a high frequency signal input from one of the high frequency transmission lines and outputs the high frequency signal to an output terminal of the other of the high frequency transmission lines. A bias supply circuit includes a trimmable chip resistor which is a variable resistor for adjusting a bias current flowing through the PIN diode. By adjusting a resistance value, the bias current flowing through the PIN diode is controlled, so that it is possible to tune the modulator characteristics.
