    摘要： In a terahertz radiation detection system, such as a terahertz camera, an array of feedhorns feeds detected radiation to diode-based mixers for mixing with a local oscillator to produce modulated intermediate frequency (“IF”) signals that can be amplified and used in imaging. The mixers are accommodated on the surface of a substrate and multiple substrates can be layered up to support a two-dimensional array of feedhorns. In order to improve packing density and thus potentially the resolution of a camera, IF filters for use in extracting the modulated IF signals are accommodated in vias through the substrates. Further, stub tuners are provided which co-operate with signal-carrying sections of microstrip to improve coupling of detected radiation and local oscillator signals to the mixers. Although the stub tuners are shared with respect to both the detected radiation and the local oscillator signals in each mixer, the involvement of the microstrips means that tuning can be optimised independently with respect to the detected radiation and to the local oscillator signals.

    摘要： The invention concerns a dwarf wave mixer realized by windowing and is characterized in that a coplanar lead (320) is produced in the plating (212) of the substrate (211), the coplanar lead (320) dividing the plating (212) into two parts; in that the coplanar lead (320) is guided out along the narrow sides of the waveguide (11, 12); in that the coplanar lead (320) is connected to each of the two parts via a first and second diode (41, 42), respectively; and in that at least two slotlines (51 - 54) are produced parallel to the broad sides of the waveguide (11, 12) in the plating (212).

    摘要： All the microwave components involved in generating, transmitting and receiving millimetric microwave signals, including transmit/receive antennae, are integrated on a single soft substrate, the only off-substrate connections comprising DC power and relatively low-frequency control signal paths. Circuit components include a DC blocking capacitor of which one plate is a portion of a strip transmission line conductor (22), the other plate is the overlapping portion of an electrode (202) of a varactor diode PILL package (20), accommodated in a correspondingly-shaped aperture in the soft substrate (210), the dielectric comprising insulating tape (212). A prismatic ferrite circulator housed in a correspondingly-shaped aperture in the substrate may be employed.

    摘要： A radio-frequency mixer and a local oscillator integrated into a single housing, and including a Gunn-type oscillator (22) coupled to the mixer by a section (14) of microstrip transmission line and a section of suspended stripline (12). A i broadside coupler in the suspended stripline provides dc and intermediate-frequency isolation forthe mixer, and a block of dielectric material on the microstrip provides improved temperature compensation for the diode oscillator. The entire compact assembly has good conversion loss performance over a relatively wide frequency band, and is relatively insensitive to temperature changes.
