Abstract: This invention relates to a modular contiguous channel multiplexer (46) having one or more modules (41, 42) that produce an asymmetric filter function that is combined with responses from other modules (44) to produce an overall symmetrical response. The multiplexer (46) can have channels (1, 2, 4) arranged in any order of relative frequencies and one or more channels (3, 5) can be added or removed from the multiplexer (46) without disturbing the operation of the existing or remaining channels (1, 2, 4). A method of constructing the multiplexer (46) involves choosing a downstream channel first, then choosing sequentially the channel immediately upstream from the channel last chosen and choosing filters (f, f1) of each channel to meet certain criteria. The filters (f, f1) of each channel are identical to one another but are not necessarily identical to filters (f, f1) in adjacent channels.

Abstract: A Beam-forming Network (BFN) includes a plurality of directional couplers (C,, C 2 , C 3 ) and phase shifters (P) which can interconnect both a transmitter and a receiver to the same group of radiating elements (1, 2, 3, 4) of an antenna even though the transmitter frequency band is different and well spaced from the receiver frequency band. This is accomplished, in accordance with the invention, by using directional couplers (C,, C 2 , C3) each of which has a variable response over a wide band of frequencies but which is designed so that its response over the transmitter frequency band is stable and its response over the receiver frequency band is also stable.

Abstract: A waveguide R-switch (44) has transformers in one or more of its three waveguide paths (34, 36, 38). The presence of the transformers allows the R-switch (44) to be constructed of a smaller size than previous R-switches with curved outer paths. This results in important weight and volume savings. Greater savings can be achieved when all three waveguide paths (34, 36, 38) contain transformers and ports (1, 2, 3, 4) of a housing (20) have dimensions that are identical to dimensions of the ends of the rotor waveguide paths (34, 36, 38), said dimensions being smaller than the interface waveguide dimensions (46) so that a transformer from the waveguide paths is integrated into each of the housing ports (1, 2, 3, 4). In a conventional manner, the R-switch (44) has a rotor that can be made to rotate through positions within the housing (20).

Abstract: A triple mode dielectric loaded bandpass filter (28) has at least one cavity (30) resonating in three independent orthogonal modes. The triple mode cavity (30) can be mounted adjacent another cavity (32) which may be either a single, dual or triple mode cavity. Any reasonable number of cavities can be used as well as various arrangements of cavities. Inter-cavity coupling is achieved through an iris (34) having two separate apertures (36, 38) that together form a T-shape. The cavities are planar mounted. The fitter (28) is designed for use in the satellite communication industry and results in substantial savings in weight and size when compared to previous filters.

Abstract: A telemetry system with a matrixed telemetry switch unit array and a method for determining the switch position of a telemetry switch unit. The switch units include steering diodes and parallel signal paths each with unique resistance values. The signal paths correspond to switch positions and are closed when the switch unit is in the corresponding switch position. A signal source is electrically connected to an input current path and output current path of the array with a corresponding telemetry switch unit coupled into the signal path. A plurality of sensing signals are applied through the array and the resultant signals are measured. The switch position is determined from the resultant signals indicating the resistance value of the switch signal path currently coupled into the array signal path while accounting for the voltage drop of the steering diodes

Abstract: A microwave switch for transmitting signals having a plurality of ports and a plurality of signal paths for selective transmission of the signals. Each signal path is disposed between a respective pair of the ports and each signal path has a conducting state in which signal transmission occurs between the respective pair of ports and a non-conducting state in which signal transmission does not occur between the respective pair of ports. The switch also has a plurality of actuators, each actuator being adapted to actuate at least one of the signal paths between the conducting and non-conducting states. At least one of the ports and at least one of the signal paths are located on a first plane and the remainder of the ports and the signal paths are located on a second plane such that there are no cross over points between the signal paths in any of the planes. A switch matrix can be built using this bi-planar switch such that the switches in the matrix are connected without any cross over points.
