摘要： Techniques are disclosed for reducing off-state leakage current in a differential switching device. The techniques can be embodied, for example, in a method that includes receiving a differential input signal at a differential input of each of a primary switch and a dummy switch. In an enabled-state of the device, the method further includes passing the differential input signal to a differential output of the primary switch. In a disabled-state of the device, the method further includes canceling off-state leakage current at the differential output of the primary switch, by virtue of the dummy switch having its differential output reverse-coupled to the differential output of the primary switch. The method may further include preventing the dummy switch from passing signals other than off-state leakage signals. The techniques can be embodied, for instance, in a switching device.

摘要： A digital or smart array antenna has at least one radio and a processor coupled to each antenna element. The processor is coupled with programmable logic that demodulates a plurality of signals received at one antenna element to obtain demodulation symbols. After obtaining the demodulation symbols, the programmable logic applies a weighting function. In this order or sequence, the digital array antenna is able to reduce the processing requirements associating within the signal information. The reduced processing requirements enable the signal information to be shared with adjacent antenna elements that may be timing adjusted between adjacent elements. Then, the sharing continues across all elements the array until the signal reaches an edge of the array. At the edge of the array, a signal beam may be generated that is steer in response to the processed signal information shared between all the elements in the array.

摘要： A bipolar pulse generator includes two, two-conductor transmission lines coupled together with a load positioned between the two transmission lines. Each conductor of a transmission line we define as a segment. Two segments of one transmission line are charged and switchably coupled to two segments of the other transmission line to produce a bipolar pulse on the matched load. This bipolar pulse generator may be implemented in a flat or a folded design. The generator may include two transmission line structures coupled together with a load positioned between each transmission line structures. The first transmission line structure may include a stepped transmission line and an embedded transmission line segment. A switch may be coupled between the embedded transmission line segment and another segment of the transmission line structure. During operation, the first transmission line structure may be charged to a potential with the switch in the open position and, when the switch is closed, the charge on the first transmission line structure together with the second transmission line structure generates a bipolar pulse on the matched load.

摘要： A synthetic crystal oscillator enables a conventional crystal to be replaced with purely active electronic elements. Stability and performance characteristics are shown to be comparable-to-superior to a conventional crystal oscillator with side-by-side simulations. The synthetic crystal oscillator with purely active electronic elements offers cost, miniaturization and performance benefits. In some examples, the purely active electronic elements include an RLC circuit generate multiple stable concentric oscillations associated with nonlinear resonance used as an oscillator without a conventional crystalline structure coupled to the electrical circuit.

摘要： GPS reception on helicopters and ground vehicles may be subject to varying near-ground interference. A compact antenna includes vertically spaced arrays of radiating elements. The first array provides a basic reception pattern. The second array provides a pattern having a distinctive low elevation angle phase reversal. By combining signals for these patterns an antenna pattern with a low angle onmidirectional elevation null characteristic is provided to suppress near-ground interference. Prior to combining, signals from the second array may be modified in amplitude or phase, or both, on a semi-permanent basis, or may be adaptively modified on an active basis, in order to adjust the null characteristic. Antennas and methods are described.
