摘要： A fixed-gain power amplifier receives a preamplifier output signal and produces a power output signal. The preamplifier output signal is amplified by the fixed-gain power amplifier to produce the power output signal. The variable-gain preamplifier receives an input signal, a preamplifier control signal, and produces the preamplifier output signal. The input signal is amplified by a preamplifier amount of gain by the variable-gain preamplifier to produce the preamplifier output signal. The preamplifier amount of gain is based on the preamplifier control signal. A variable attenuator receives the power output signal, an attenuator control signal, and produces an output signal. The power output signal is attenuated by an attenuator amount of attenuation by the variable attenuator to produce the output signal. The attenuator amount of attenuation is based on the attenuator control signal.

摘要： In a wireless communication device, circuitry selects a first frequency band for a first wireless communication and transfers a pair of radio frequency signals at the first frequency band. An antenna receives and orthogonally transmits the radio frequency signals over a first patch antenna element that is resonant at the first frequency band. The circuitry selects a second frequency band for a second wireless communication and transfers a pair of radio frequency signals at the second frequency band and including a voltage component. The antenna receives the radio frequency signals including the voltage component, couples a second patch antenna element to the first patch antenna element in response to the voltage component, and orthogonally transmits the radio frequency signals over the coupled patch antenna elements that together are resonant at the second frequency band.

摘要： A gyroscope monitoring system operates with an antenna system that has a gyroscope that controls the position of multiple antennas. The monitoring system receives data indicating reference signal strengths and test signal strengths for the antennas. The monitoring system determines differences between the reference signal strengths and the test signal strengths. The monitoring system processes the differences to determine if the gyroscope has lost reference point accuracy, and if so, then the monitoring system generates an indication that the gyroscope has lost reference point accuracy. In some examples, the monitoring system also determines reference point offsets for the gyroscope and provides the offsets to the gyroscope for use in motion measurements.

摘要： A time-division communication system wirelessly receives a communication signal during receive time periods and wirelessly transfers a communication signal during transmit time periods. These communication signals have multiple receive and transmit channels. The communication system circulates the received communication signal to various filters that pass particular receive channels and that reflect other receive channels back the circulator(s). Eventually, the reflected receive channels circulate to the appropriate filters and are passed. The filters also pass transmit channels to the circulator(s) where they are circulated and reflected until they combine into the transmit communication signal.

摘要： A system and method for receiving a communication signal includes a timing source that generates a stable timing signal and a stabilized local oscillator that receives the stable timing signal and uses the stable timing signal as an input to generate a stabilized oscillator signal. An antenna receives the communication signal at a receiving frequency, and the communication signal is filtered and amplified. A low noise block converter uses the stabilized oscillator signal to convert the receiving frequency of the communication signal to a stable lower frequency. A fiber optic transmitter converts the communication signal to an optical signal and transmits the optical signal over fiber optic cable. A fiber optic receiver receives the optical signal over the fiber optic cable. The optical signal then can be converted to an electrical signal.
