A first conductor pattern (51) is disposed in a direction nearly vertical to first dielectric strips (31a, 31b) which constitute a first NRD guide, first and second filter circuits (6, 7) are provided at positions at which the dielectric strips (31a, 31b) are sandwiched, thus forming a first resonance circuit, and beam lead diodes (81, 82) are mounted in series within the resonance circuit. Further, a second conductor pattern (52) is extended from the nearly central position of the filter circuits (6, 7), and a third filter circuit (9) is provided, thus forming a second resonance circuit. A second NRD guide based on second dielectric strips (32a, 32b) is connected to the second resonance circuit.

    摘要: There is described an image rejection frequency converter comprising essentially a balun (DIV) used as a power divider for coupling a local oscillator signal to the ends of two frequency mixers (MIX1, MIX2). Said mixers (MIX1, MIX2) have ports to which arrive or from which come out intermediate radiofrequency signals (Fig. 1).
    The invention consists principally of integration of the power divider (DIV) and the mixers (MIX1, MIX2) in a planar structure based on a new concept provided in microstrip and in coplanar line.

    摘要: A compact multi-layer flat antenna structure incorporating a low noise block down-converter on the power divider network layer of the antenna. RF circuit losses are reduced, and the antenna/­receiver combination is made more compact, for flush mounting. The antenna/receiver combination finds particular utility in direct broadcast satellite (DBS) applications for single or dual orthogonal polarizations. The connection between the antenna and receiver may be implemented in stripline/ coplanar waveguide, or other known technologies such as microstrip, slotline, and finline.

    摘要: A finline detector (100 or 110) comprises a dielectric substrate-mounted circuit disposed within a millimeter waveguide, said substrate circuit comprising a substrate (114) with a diode (224) mounted thereon in series with the waveguide (16). The mounting of a diode (224), which may have a characteristic impedance substantially lower than the characteristic impedance of a realizable finline, in series with the waveguide transmission line minimizes sensitivity to the high capacitance and therefore low impedance realizable with such a detection diode. Furthermore, the transmission line may be terminated more easily in a wideband termination (50), thus increasing the effective bandwidth of operation of the detector. Two representative embodiments of the invention are, for example, an unbalanced detector (100) and a balanced detector (110). Each embodiment includes a detection device, namely a diode (224, 324), coupled in series with the finline transmission line (101). Capacitance means (34,134,36,136,38,138) are also provided.

    摘要: A combined duplexer/mixer especially for use in an FMCW millimetric radar system has a waveguide section containing a fin line or suspended strip structure for responding to the linearly polarised radar return signal passing through the section in one direction while permitting passage of the orthogonally polarised, outgoing signal passing in the other direction. The fin line is coupled via double balanced mixer diodes to an IF output line to produce an IF signal by mixing the return signal with a portion of the outgoing signal tapped off by a field distorting probe, ridge section or like coupling means.
