    摘要: A method for using the same input/output pin on an integrated circuit ("IC") for both a high frequency AC signal and a DC signal simultaneously and a first circuit means to accomplish this multiplexing is disclosed. The circuit topology comprises a first and second capacitor, coupled between the AC signal input and the AC signal output. A first and second resistor are coupled to the same input/output pin as the capacitors but between the two capacitors and respectively to a DC signal input and DC signal output. The DC signal path thus lies between the two capacitors and sees them as open circuits, while the AC signal path sees the two resistors as open circuits and the capacitors as short circuits.

    摘要: A hybrid band intelligent backhaul radio (HB-IBR) is disclosed that is a combination of two radios operating in different bands. Embodiments include a dual radio configuration wherein a first radio operates in a non-line of sight (NLOS) radio link configuration and a second ancillary radio operates in a near line of sight or line of sight configuration (n)LOS. For example, the HB-IBR may have an Intelligent Backhaul Radio (IBR) operating in the non-line of sight mode of operation within the 5.8 GHz unlicensed band, and have an ancillary radio link operating in the FCC part 101E band of operation at 60 GHz. A common medium access control (MAC) block may be utilized between the dual radios.

    摘要: A frequency translating repeater (120) for use in a time division duplex (TDD) radio protocol communications system includes local oscillator (LO) circuits (210, 310, and 410) to facilitate repeating by providing isolation, reduced phase noise, reduced pulling, and the like. Tunable LOs (441, 442) can be directly coupled to down-converters (413, 414) and up-converters (426, 427) for increased isolation, reduced phase noise, less stringent frequency accuracy, and a reduced potential for pulling.

    摘要: A synchronous, interleaved, time-division 1:M demultiplexor uses M equally-spaced phases of a clock signal having a frequency of B/M to latch M incoming serial data bits (where B is the incoming bit rate and M is an integer power of two equal to or greater than four). Following an input stage of parallel synchronous latches, an intermediate stage of parallel synchronous latches is used in which the intermediate latches are clocked with selected phases of the M-phase clock to latch each bit at a time at least 2/B (i.e., two incoming bit periods) after such bit is received from its respective input latch. Following the intermediate stage of parallel synchronous latches, an output stage of parallel synchronous latches is used in which the output latches are clocked with at least one selected phase of the M-phase clock to latch each bit at a time at least 2/B after such bit is received from its respective intermediate latch.

    摘要: A synchronous, interleaved, time-division M:1 multiplexor. Following an input stage of parallel synchronous latches for latching M incoming parallel data bits (where M is an integer power of two equal to or greater than four) is an intermediate stage of parallel synchronous latches. The intermediate latches are clocked with selected phases of an M-phase clock having M equally-spaced phases of a clock signal having a frequency of B/M (where B is the outgoing bit rate) to latch each bit at a time at least 2/B (i.e., two outgoing bit periods) after such bit is received from its respective input latch. A first stage of 2:1 multiplexors, following the intermediate latches and used to begin multiplexing the latched bits, are clocked with selected phases of the M-phase clock to begin multiplexing each bit at a time at least 1/B (i.e., one outgoing bit period) after such bit is received from its respective intermediate latch. Further stages of 2:1 multiplexors complete the multiplexing and are each clocked with clock signals which are successively doubled in frequency at each additional stage of 2:1 multiplexors (e.g., 2B/M, 4B/M, 8B/M, . . . ) and phase compensated so as to align the clock signals with their respective data. The phase-compensated, frequency doubling for each 2:1 multiplexor stage is done by "exclusive-ORing" pairs of quadrature clock signals from the immediately preceding 2:1 multiplexor stage.

    摘要: Directive gain antenna elements implemented with an aperture-fed patch array antenna assembly are described. A feed network for the aperture-fed patch array may include offset apertures and may also include meandering feed lines. Scalable aperture shapes and orientations that can be used with antennas operating at any frequency and with dual orthogonal polarizations are also disclosed. Directive gain antenna elements implemented with arrays of orthogonal reflected dipoles are also described with optimal feed networks and parasitic elements to achieve desired directive gain characteristics. Such arrayed dipole antennas feature dual orthogonal polarizations with assembly tabs that lower cost and improve reliability. Backhaul radios that incorporate said antennas are also disclosed.
