    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 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 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.
