Attenuators play an important role in the field of electric engineering and communication technology. One of the attenuators is PXV1220S-6DBN8-T, with application field and working principle as mentioned in this article.

PXV1220S-6DBN8-T is a high performance variable attenuator which has a frequency range up to 26.5GHz. It has an insertion loss of 0.5dB and an isolation of 32dB. The PXV1220S-6DBN8-T has a miniaturized package of 16.5*13.3mm and a VSWR as low as 1.3:1. It is a cost effective and reliable solution for high speed, high frequency applications.

The PXV1220S-6DBN8-T\'s application field covers millimeter wave point–to–point communication systems, VSAT systems, satellite links, and more, which can serve as an amplifier or attenuator. It is also widely used in CATV, microwave communications and other high frequency systems.

PXV1220S-6DBN8-T has two metal plates as contact poles which can adjust the attenuation effect according to user requirements. It adopted covering structure, which makes it easy to operate. Its working principle is a type of voltage controlled attenuator, controlled by an AC signal, using a resistance bridge to adjust the attenuation effect. Which in a resister bridge the power source is separated electronically. The effect of the resistor bridge is a DC voltage output with its amplitude and phase change with the input signal. The resistor bridge output on the bridge arm, the AC voltage is directly proportional to the amplitude of the resistance bridge. The resistance bridge is used to adjust the attenuation effect by adjusting its resistance.

In addition, it has a flat frequency response and high repeatability. The control voltage of the attenuator is adjustable, ranging from 0 to 10V, making it an ideal device to achieve isolation and signal modulation. It is small, light, and has a low power consumption. This has a working temperature ranging from -25 to +85 degree celsius.

In conclusion, PXV1220S-6DBN8-T is an ideal device for millimeter wave point–to–point communication systems, VSAT systems, satellite links, and CATV, microwave communications and other high frequency system. It has a small size and low power consumption, and is easy to operate with its covering structure.
