AT-108V Application Field and Working Principle

Introduction to AT-108V

AT-108V is a versatile 300W high power voltage programmable attenuator designed to provide two-way attenuation of the desired signal level with a variable input range that can be adjusted from 0 to -30dB. The AT-108V is capable of operating at a wide range of input power levels, from low power CW signals up to high performance multiplexed pulsed launches. It can be used within a variety of industries, such as cellular, broadcast, cable television, wireless and satellite communications.

Working Principle

The AT-108V attenuator works based on a DC current amplifier circuit. The DC current is used to adjust the input signal amplitude. The input signal passes through the DC current amplifier circuit, where a correction factor is applied to the amplitude of the signal. This correction factor is used to reduce or increase the signal level, depending on the desired application. Users can adjust the input signal level from 0 to -30 dB.

Additionally, the AT-108V attenuator utilizes a noise blanker which eliminates any unwanted interference. The noise blanker feature ensures that only the desired attenuated signals pass through and result in high quality output. The attenuator also contains protection circuitry which helps protect against any power fluctuations.

Application Fields

The AT-108V attenuator is a highly versatile device, suitable for a variety of applications. In particular, it is an ideal solution for applications requiring over-the-air or satellite transmission, where the signal level needs to be adjusted according to the desired output. Additionally, it is suitable for applications that require precise signal level and noise blanker, such as in cellular and broadcast systems.

The AT-108V attenuator is also suitable for amplifying the signal level in wired transmissions, such as in cable television or fiber optics. It can be used to boost the signal level of long cable runs, where the signal quality needs to be kept at an optimal level. Furthermore, the attenuator can be used in laboratory measurement equipment, to adjust the signal amplitude for fine-tuning the accuracy of the results.

Conclusion

The AT-108V attenuator is a versatile device that can be used in a variety of fields, including cellular and broadcast communications, cable television and laboratory equipment. It is highly reliable and contains features such as a noise blanker and protection circuitry, which ensures a quality output. Furthermore, the attenuator is capable of producing a variable input range from 0 to -30dB, making it suitable for applications requiring precise signal control.
