摘要： Apparatus and methods are provided for ameliorating distortion issues associated with a conductor that passes over a void in a reference plane. In an example, the conductor can include a first part routed over a major surface of a first side of the reference plane structure and that approaches a first edge of the reference plane structure with a first trajectory, a second part routed over the major surface of a second side of the reference plane structure and that approaches a second edge of the reference plane structure with a second trajectory in-line with the first trajectory, and a third portion connecting the first portion with the second portion and having a third trajectory departing from the first trajectory and the second trajectory, the third portion configured to span the void.

摘要： A beam former module includes a package base and an interconnect structure formed within the package base. The beam former module also includes a first true time delay (TTD) module attached to the package base. The first TTD module includes a plurality of switching elements configured to define a signal transmission path between a signal input and a signal output of the first TTD module by selectively activating a plurality of time delay lines. The signal input and the signal output of the first TTD module are electrically coupled to the interconnect structure. In some embodiments, the interconnect structure includes at least one TTD meander line and at least one of the time delay lines of the first TTD module is electrically coupled to the at least one TTD meander line.

摘要： A transmission line is provided with a fixed physical length and a programmable electrical length for achieving a programmable time delay. The transmission line can include a dielectric and a biasing device disposed across the dielectric, and the biasing device can dynamically and continuously vary an absolute level of a bias voltage across the dielectric to vary a dielectric constant of the dielectric, which can vary a time delay of the transmission line. In some embodiments, the biasing device can modulate the bias voltage from a positive voltage to a negative voltage at a frequency and with waveform characteristics that prevent such modulation from interfering with a signal propagating through the dielectric, that prevent the bias voltage from unintentionally varying the time delay of the transmission line when the absolute level of the bias voltage is constant, and that prevents ion impurities within the dielectric from accumulating on bias electrodes.

摘要： A package trace design technique provides at least partial cancelation of reflections. In one illustrative method of providing a high-bandwidth chip-to-chip link with a first die coupled to a second die via a first substrate trace, an intermediate trace, and a second substrate trace, the method includes: (a) determining a first propagation delay for an electrical signal to traverse the first substrate trace, the electrical signal having a predetermined symbol interval; (b) determining a second propagation delay for the electrical signal to traverse the second substrate trace; and (c) setting a length for at least one of the first and second substrate traces, the length yielding a difference between the first and second propagation delays, the difference having a magnitude equal to half the predetermined symbol interval.

摘要： An improved active, electronically scanned array antenna that employs programmable time delays in the transmission feed lines to form timed arrays is provided. A timed array can be implemented as a nested set of transmission lines, and the programmable time delay can be realized as or in each of the transmission lines such that each transmission line can have a fixed physical length and a programmable electrical length.

摘要： A passive circulator utilizing sequentially-switched delay lines (SSDL) in which delay line sections are sequentially turned on and off to achieve non-reciprocity to provide rejection/separations between different signals at the same/similar frequency, such as between a transmitted and received signal. The circulator is well-suited for on-chip integration and can be utilized across a wide frequency range. Various embodiments are described for separating signal waveforms.

摘要： The present disclosure relates to a tunable slow-wave transmission line. The tunable slow-wave transmission line is formed in a multi-layer substrate and includes an undulating signal path. The undulating signal path includes at least two loop structures, wherein each loop structure includes at least two via structures connected by at least one intra-loop trace. The undulating signal path further includes at least one inter-loop trace connecting the at least two loop structures. The tunable slow-wave transmission line includes a first ground structure disposed along the undulating signal path. Further, the tunable slow-wave transmission line includes one or more circuits that may alter a signal transmitted in the tunable slow-wave transmission line so as to tune a frequency of the signal.
