What is a phase controller?
Phase controller is a device that can change the phase angle of radio frequencies or microwave signal. Most phase shift devices are compatible with signals regardless of their direction and classify them like mutual networks. Phase controllers can be controlled electrically, mechanically and magnetically. They are available in analog form to allow a variable phase or time delay that occurs continuously, and a digital phase or delay set. Different types also include a phase series variable or a switched line, a pickled line, a reflection phase and a microwave phase. Most often, phase controllers are digital and also include voltage control that provides noise or interference immunity. The signal phase states are controlled by the digital phase bits. Each following phase is the half angle of the last, so the 2 -bit device would be 90 degrees of shifting, because the 180 degrees is the highest in the range and categorizes the signal moving in a straight line. Neopen-State device is determined by the lengthPhase covering the shortest distance, while the longest phase length is condition.
Analog phase shifting offers a continuous phase change with continuous shift. The input of variable control that supports unlimited phase resolution may also be included. Even the microwave phase controller can be analog or digital and controlled by a semiconductor device such as a diode. The circuit itself is designed to move the microwave signal to the maximum level, so that the device and circuit specification should be considered before adding to the system. The phase shift is selected on the basis of application requirements and mathematical calculations, what properties are needed in the signal.
As with most electronics, energy -saving force is an important characteristic of the phase changing device. The passive phase controller is not consumed by any power that performs the required operation automatically without external control. Low loss is anotherThe energy saving feature and loss can be even more reduced by inclusion of the amplifier phase in the phase shift. The device variants include a gear line that includes two single -pound double -hour switches to switch two electrical lines of different lengths. The shiftery phase -loaded lines are configured for shifts less than 45 °, while the reflective phases use the line lengths that switch to change the length of the electrical paths.
