摘要： This invention eliminates the need for “capacitor coupling” or “transformer coupling,” and the associated undesirable parasitic capacitance and inductance associated with these coupling techniques when designing high frequency (˜60 GHz) circuits. At this frequency, the distance between two adjacent stages needs to be minimized. A resonant circuit in series with the power or ground leads is used to isolate a biasing signal from a high frequency signal. The introduction of this resonant circuit allows a first stage to be “directly coupled” to a next stage using a metallic trace. The “direct coupling” technique passes both the high frequency signal and the biasing voltage to the next stage. The “direct coupling” approach overcomes the large die area usage when compared to either the “AC coupling” or “transformer coupling” approach since neither capacitors nor transformers are required to transfer the high frequency signals between stages.

摘要： A portable unit with an endfire antenna and operating at 60 GHz makes an optimum communication channel with an endfire antenna in an array of antennas distributed over the area of a ceiling. The portable unit is pointed towards the ceiling and the system controlling the ceiling units selects and adjusts the positioning of an endfire antenna mounted on a 3-D adjustable rotatable unit. Several transceivers can be mounted together, offset from one another, to provide a wide coverage in both azimuth direction and elevation direction. These units can be rigidly mounted as an array in a ceiling, apparatus. The system controlling the ceiling array selects one of the transceivers in one of the units to make the optimum communication channel to the portable unit. The system includes the integration of power management features by switching between Wi-Fi in favor of the 60 GHz channel.

摘要： Processors are arranged in a pipeline structure to operate on multiple layers of data, each layer comprising multiple groups of data. An input to a memory is coupled to an output of the last processor in the pipeline, and the memory's output is coupled to an input of the first processor in the pipeline. Multiplexing and de-multiplexing operations are performed in the pipeline. For each group in each layer, a stored result read from the memory is applied to the first processor in the pipeline structure. A calculated result of the stored result is output at the last processor and stored in the memory. Once processing for the last group of data in a first layer is completed, the corresponding processor is configured to process data in a next layer before the pipeline finishes processing the first layer. The stored result obtained from the next layer comprises a calculated result produced from a layer previous to the first layer.

摘要： In an up-converter path of a transmitter, wide-band signal system like direct. conversion WiGig, a high pass filter (HPF) is placed in the baseband path after the low pass filter (LPF) but before the mixers. The baseband signal of WiGig can have a bandwidth of 800 MHz. The HPF removes the frequencies from 0-40 MHz from the baseband signal and degrades the overall signal of the baseband by a dB or so. However, the frequency pulling is significantly reduced since oscillator frequency and Radio frequency (RF) transmitter frequencies after conversion become further separated when compared a system using to the conventional approach. This causes the injected signal to fall outside the locking range of the oscillator. The concern of substrate coupling is reduced and allows for a reduction in the physical distance between the oscillator and the mixer and reduces a shift in the desired target frequency of operation.

摘要： A cross coupled NMOS transistors providing a negative gm transistor feedback allows a mixer to saturate at a reduced input signal swing voltage when compared to a conventional mixer allowing the mixer to enter into the current mode operation at a reduced signal input voltage range. The linearity of the baseband signal path can be traded against the mixer gain and is improved if the signal swing in the baseband signal path is reduced. The input mixer transistors operate in the saturated mode at a reduced input signal swing voltage causing the power efficiency of the system to increase since the transmit chain operates at a class-D power efficient. Efficiency is very important in mobile applications to save and extend the battery power of a mobile phone providing a better utilization of the available power since most of that power is supplied to the energy of the outgoing modulated signal.

摘要： The class-E amplifier can be tuned to pass only the fundamental frequency to the antenna by optimizing the second harmonics at the drain of the final PA driver transistor. A CPW in series with a capacitor between the PA transistor and the load forms a band pass filter that only allows the fundamental frequency to pass to the load of the antenna. A supply inductor to couple the drain of the final PA driver transistor to the power supply is tuned at the second harmonic with the parasitic capacitance of the drain of the PA transistor. A load capacitance is adjusted at the fundamental frequency to insure that the current waveform and voltage waveforms at the drain of the PA driver transistor do not overlap, thereby minimizing the parasitic power dissipation and allowing maximum energy to be applied to the antenna.

摘要： The LTCC (Low Temperature Co-fired Ceramic) substrate is used to form an antenna structure operating at 60 GHz. The dielectric constant is high and ranges from 5 to 8. The substrate thickness is fabricated with a thickness between 360 μm to 700 μm. The large dielectric constant and large thickness of the substrate creates a guiding wave in the LTCC that forms an endfire antenna. A high gain signal of 10 dB in a preferred direction occurs by placing the microstrip fed dipole structure in the center of the LTCC substrate creating a dielectric cavity resonator. The creation of a slot in the LTCC substrate between the two microstrip fed dipole structures eliminates beam tilting and allows for the two microstrip fed dipole structures to reduce the coupling to each other thereby providing substantially two isolated endfire antennas. These antennas can be used as multiple receive or transmit antennas.

摘要： A cascode common source and common gate LNAs operating at 60 GHz are introduced and described. The cascode common source LNA is simulated to arrive at an optimum ratio of upper device width to the lower device width. The voltage output of the cascode common source LNA is translated into a current to feed and apply energy to the mixer stage. These input current signals apply the energy associated with the current directly into the switched capacitors in the mixer to minimize the overall power dissipation of the system. The LNA is capacitively coupled to the mixer switches in the I and Q mixers and are enabled and disabled by the clocks generated by the quadrature oscillator. These signals are then amplified by a differential amplifier to generate the sum and difference frequency spectra.
