MS grating adopts silicon micromachining technology.

MEMS (Micro-Electro-Mechanical System) is developed on the basis of microelectronics technology (semiconductor manufacturing technology), which integrates high-tech manufacturing technologies such as lithography, corrosion, thin film, LIGA, silicon micromachining, non-silicon micromachining, and precision machining. Technological electronic mechanical devices. Aigtek power amplifiers can drive various MEMS system devices. Common products include MEMS microphones, micro motors, micro pumps, micro vibrators, MEMS optical sensors, MEMS pressure sensors, and so on.

MEMS grating application test:

MEMS grating adopts silicon micromachining technology. Under the action of external force, some characteristic parameters of the grating (such as period, grating and other constants) are changed, so as to change the working performance of the grating in real time and realize the programmable application of the grating. MEMS gratings have a variety of driving methods. Electrostatically driven MEMS gratings are the most commonly used driving method because of their easy-to-implement process, low energy consumption, and high frequency response.

The energy density of electrostatic drive is relatively small. When the structure requires a relatively large working displacement (micron level), the drive voltage must be increased, and the drive voltage can even reach hundreds of volts. The Aigtek power amplifier can output a voltage range of 200Vpp~1600Vpp and a current output capability of 40mA~500mA, which can meet the dynamic driving test of new MEMS related applications. Based on its unique advantages, MEMS gratings have been used in fields such as optical communications, high-definition display devices, and spectral analysis.

ATA-2000 series power amplifiers can output ideal single-ended and differential signals, providing a quick tool for research in the MEMS field. At the same time, this series of power amplifiers are designed with good over-voltage, over-current, and short-circuit protection devices. At the same time, in order to better provide a complete impedance matching network for MEMS test customer applications, it is convenient for users to choose the corresponding matching impedance.

ATA-2042 power amplifier is a broadband dual-channel high-voltage power supply product produced by Aigtek, with a voltage range (0-400Vpp), stable output voltage, current, dual-channel synchronous output, etc., as well as over-current and over-temperature protection functions. Suitable for driving high-voltage loads, can amplify AC and DC signals, output current 100mA, voltage gain is adjustable from 0 to 60 times by digital control, LCD screen display, one-key save common settings, can be used with any brand signal generator, realize any Perfect amplification of waveform signals.
