摘要： An asynchronous receiver system has multiple antennae and an asynchronous receiver circuit with a signal input. The asynchronous receiver circuit receives a wireless signal at the signal input and generates a first quality signal responsive to the received wireless signal. A switch selects one of the antennae for coupling to the input of the asynchronous receiver circuit responsive to a control signal. A controller receives the first quality signal and generates the switching control signal. The controller sequentially selects each one of the antennae, measures the first quality signal and starts a timer with a time value for the selected antenna. The controller selects a next one of the antennae if the measured first quality signal value is below a threshold value and the timer expires and receives a remainder of a data packet based on the measured first signal quality values for the plurality of antennae.

摘要： A modulated intermediate frequency receiver is shown having a low noise amplifier for receiving a radio frequency signal and a modulation source for generating a modulation signal. A local oscillator generates a modulated local oscillator signal in response to the modulation signal. A first mixer mixes the output of the low noise amplifier with the output of the local oscillator. The output of the mixer is DC filtered and receive bandwidth filtered before input to a demodulator that generates a demodulated received signal. Further embodiments are shown for a complex receiver and having phase or frequency modulation compensation.

摘要： A frequency hopping coordinator device scans a plurality of frequencies for request for services messages during an unused time slot in order to detect a request for service preamble on one of the frequencies and, responsive thereto, send a service packet message to an end device from which it received the request for service message on the one frequency. The service packet includes a current frequency sequence value of the coordinator device's pseudo-random number sequence and beacon timing information that indicates when periodic beacon messages occur. An endpoint device sends a request for services message on a first frequency of the plurality of frequencies scanned by the coordinator device that includes a preamble identifiable by the coordinator device. The endpoint device receives the service packet message and, responsive thereto, changes the end point's current frequency sequence value and timing information to match the values sent by the coordinator device.

摘要： A method and circuit for receiving a radio frequency signal by receiving and amplifying the radio frequency signal to produce a received signal and generating first and second clock signals corresponding to first and second channel signals, respectively, of the received signal and multiplying the received signal with the clock signals to obtain the channel signals. Pre-selectivity filtering of the received signal is performed by filtering the first channel using a first impedance, filtering the second channel using a second impedance, and converting the first and second impedances with respect to one another through a first gyrator. Amplitude limiting of the first and second channels is performed to obtain first and second amplitude limited channels. Poly-phase selectivity filtering of the first and second amplitude limited channels is performed to obtain first and second selectivity filtered channels. The selectivity filtered channels are demodulated to obtain a data signal.

摘要： Using two simple antennas with different frequencies of operation combined into an antenna arrangement a directional radiation pattern is obtained for both frequencies of operation. This is achieved by placing the antennas such that the first antenna acts as a director for the second antenna at the frequency of operation of the second antenna and the second antenna acts as a reflector for the first antenna at the frequency of operation of the first antenna. In the case of a monopole antenna the the first antenna is shorter than the second antenna and can thus operate as a director while the second antenna is longer than the first antenna and can thus act as a reflector.
