A dielectric substrate (2) is provided with a conductor layer (3) disposed parallel with the dielectric substrate (2), first and second planar lines (4, 5) each containing a part of the conductor layer (3), and a waveguide (6) containing a part of the conductor layer (3). The first and second planar lines (4, 5) are located on one surface (2a) side of the dielectric substrate (2) with respect to the conductor layer (3), and the waveguide (6) is located on another surface (2b) side of the dielectric substrate (2). In a transmission direction (X) of electric signals, as to the waveguide (6), its one end overlaps with one end of the first planar line (4), and its another end overlaps with one end of the second planar line (5). In the overlapped regions, first and second through-holes (24, 25) are so formed as to penetrate the conductor layer (3) in its thickness direction.

Abstract: A millimeter-wave transmitter-receiver uses an NRD guide as a fundamental configuration and includes a millimeter-wave signal oscillator, a pulse modulator, a circulator, an antenna and a mixer. In the millimeter-wave transmitter-receiver, a line length of a third dielectric guide is set so that δ=±π in which δ is a phase difference at a center frequency between a portion of a transmission millimeter-wave signal, which is reflected via a third dielectric guide on the leading end portion of the third dielectric guide and returned to leak to a third connecting portion of the circulator, and another portion of the millimeter-wave signal, which leaks from a first connecting portion to the third connecting portion of the circulator. It is possible to reduce the change in the mixer output and enhance the millimeter-wave transmission/reception performance.

Abstract: Provided is a millimeter-wave transmitting/receiving apparatus of pulse-modulation type in which pulse-modulated millimeter-wave signals for transmission are prevented from being outputted to a reception system due to inner reflection or other causes. Included are: an NRD guide (basic structure) formed of a dielectric line sandwiched between parallel plate conductors; a millimeter-wave signal oscillator; a pulse modulator; a circulator; a transmitting/receiving antenna; and a mixer. At the output end of the mixer is disposed a switching device which interrupts intermediate-frequency signals in an opened state, and, when a millimeter-wave signal for transmission from the pulse modulator enters a non-output state and the condition is stabilized, changes into a closed state to pass intermediate-frequency signals. The intermediate-frequency signal containing noise resulting from the millimeter-wave signal for transmission entering the mixer can be prevented from leaking toward downstream side of the mixer; wherefore a desired intermediate-frequency signal can be outputted.

Abstract: A mixer capable of keeping mixing characteristics tuned satisfactorily is provided. A coupler includes two input ends, and one or two output ends. At the output end is disposed a Schottky-barrier diode acting as a high-frequency detection element. Connected to the Schottky-barrier diode is a bias supply circuit having a trimmable chip resistor acting as a pre-set variable resistor, for controlling a bias current which passes through the Schottky-barrier diode. By adjusting the resistance of the trimmable chip resistor, it is possible to control a bias current passing through the Schottky-barrier diode, and thereby keep mixing characteristics tuned satisfactorily.

A high-frequency oscillator includes a Gunn diode serving as a high-frequency oscillation element that generates high-frequency signals, a resonator connected to the Gunn diode, a varactor diode serving as a variable-capacitance element that is disposed on the resonator and changes a resonance frequency, and a bias supply circuit that is connected to the varactor diode and supplies a bias voltage applied in order to change a capacitance. The bias supply circuit includes a trimmable chip resistor serving as a pre-set variable resistor that regulates a bias voltage applied to the varactor diode. By regulating the resistance value of the trimmable chip resistor, it is possible to control the capacitance value of the varactor diode and tune oscillation characteristics to a desired state.
