摘要： A technique for performing adaptive predistortion in a transmitter includes receiving, at a first input of an error signal unit, a delayed version of a baseband input signal. The technique also includes receiving, at a second input of the error signal unit, a power amplifier feedback signal from an output of a power amplifier. An input error signal that corresponds to a difference between the delayed version of the baseband input signal and the power amplifier feedback signal is then provided at an output of the error signal unit. The input error signal is then received at an input of a signal conditioner. An adjusted error signal that has a lower direct current offset than the input error signal is provided at an output of the signal conditioner.

摘要： Embodiments include methods and apparatus for performing transmit power control. A gain application element receives a sequence of digital input samples and a digital gain signal, and combines the digital gain signal with the digital input samples to generate a sequence of gain-compensated digital samples. A power amplifier receives and amplifies an analog version of the gain-compensated digital samples in order to generate an antenna output signal. A feedback path generates an analog feedback signal from the antenna output signal, produces a sequence of digital feedback samples from the analog feedback signal, and generates difference values based on the digital feedback samples. When a specified type of constant modulus symbol is represented in the antenna output symbol, the feedback path accumulates the difference values into an accumulated error value, and produces the digital gain signal from the accumulated error value.

摘要： A power circuit includes a control unit, a logic control circuit, a first driver amplifier, a second driver amplifier and a logic determination circuit. The control unit is used to output a pulse width modulation (PWM) signal and an enable (EN) signal. The logic control circuit receives the PWM signal and the EN signal, and outputs a first voltage signal and a second voltage signal. The first driver amplifier receives the first voltage signal, and outputs a first gate (UGATE) drive signal. The second driver amplifier receives the second voltage signal, and outputs a second gate (LGATE) drive signal. The logic determination circuit receives the PWM signal and the first and second gate drive signals. When the PWM signal and the first and second gate drive signals meet an abnormal logical relation, the logic determination circuit disables the logic control circuit.

The inlet hole, the two outlet holes and the two connecting holes communicate with the valve chamber, respectively. The valve plug is slidably assembled within the valve chamber of the valve body, and operating in one of three different working states of the control valve. The valve plug defines a first lock slot, an intermediate slot and a second lock slot. The block mechanism is adjustably assembled to the valve body and selectively received and engaged in one of the first lock slot, the intermediate slot or the second lock slot, in which each position of the valve plug establishes one of the three working states of the control valve.

摘要： Embodiments include transmitters, wireless devices, and methods for performing loop delay and gain control. In a transmitter, a gain application element receives and combines digital input samples and a digital gain signal to generate gain-compensated digital samples. A power amplifier receives and amplifies an analog version of the gain-compensated digital samples to generate an antenna output signal. A feedback path generates an analog feedback signal from the antenna output signal, to produce a sequence of digital feedback samples from the analog feedback signal, and generates the digital gain signal from the sequence of digital feedback samples and a loop gain estimate. A loop delay and gain calculator calculates a loop delay estimate from the gain-compensated digital samples and the sequence of digital feedback samples, and calculates the loop gain estimate using the loop delay estimate, the gain-compensated digital samples, and the sequence of digital feedback samples.

摘要： An adhesion bond between a metallic surface layer and a second surface is formed by treating the layers with a material comprising sulphur-containing molecules. The sulphur-containing molecules are applied as a surface treatment of the surfaces, so that the sulphur-containing molecules act as a coupling agent to bond chemically to both substrates form nanometer-sized structures on the surfaces. The nanometer-sized structures are incorporated into a self-assembly interlayer in between the surfaces, with the interlayer forming a bond to both surfaces.
