Abstract: An application-specific wireless communication network for use in an industrial environment based on parameters defined by the IEEE 802.11 standard, modified by providing software-defined control of an assigned operating frequency band and software-defined control of the channel size, allowing the channel size to be relatively small as appropriate for the particular industrial application. The application-specific wireless communication network further controls other parameters defined by the standard to configure at least optimum transmitter power, receiver sensitivity, transmission latency, and ACK-retransmit to values appropriate for the specific industrial application.

Abstract: A radio module is configured to operate within a specialized frequency band, for example a band that has recently become available for use in the public domain. Superheterodyne techniques are used by a transmitter component of the radio module to frequency shift a conventional wireless data signal (e.g., used for WiFi, LTE telecommunications, etc.) into a designated band; a receiver component of the radio module is similarly configured to receive signals transmitted on the designated band and shift back into the conventional RF band (where standard components are able to further process the received signal).

Abstract: A method of reducing stress in a cascode common-source amplifier including a first transistor and a second transistor connected in a cascode arrangement. The method includes providing an input voltage and a bias voltage to the first transistor and the second transistor, respectively, connected in the cascode arrangement, generating, based on the input voltage and the bias voltage, an output current, and equalizing stress associated with operation of each of the first transistor and the second transistor. Equalizing the stress includes, in response to the input voltage decreasing by an amount sufficient to cause the first transistor and the second transistor to turn off, equalizing respective voltage drops across the first transistor and the second transistor.

Abstract: An amplifier system comprises a cascode common-source (CS) amplifier including a plurality of transistors connected in a common-source configuration. A stress reducing circuit is connected to at least one of the plurality of transistors to equalize a voltage drop across the plurality of transistors. The stress reducing circuit includes a first transistor including a control terminal, a first terminal and a second terminal. The second terminal of the first transistor is connected to a first terminal of a first one of the plurality of transistors. A capacitance has a first terminal connected to the control terminal of the first transistor and a second terminal connected to a control terminal of a second one of the plurality of transistors.
