HV-AT(10)-PJ

Application Field

HV-AT attenuators type PJ are suitable for both short-term and long-term use in various applications involving high-frequency, high-voltage or high-power RF signals. They can be used in aerospace and marine communications, broadcast, wireless infrastructure, antennas, and satellites.

These devices, which are self-contained and feature exceptional thermal and electrical stability, can operate over extended period of time while maintaining their level of attenuation. They are available in frequency ranges from 9kHz to 11GHz with maximum power ratings from 500W to100W.

HV-AT type PJ attenuators are designed to accurately measure peak RF voltages or powers and to achieve fine control over the signal level. This type of attenuator is suitable for most RF systems and can be used in a broad range of radiofrequency applications.

Working Principle

The working principle of HV-AT attenuators type PJ is based on the use of a series of two or more layers of material, typically non-Ionizing Radiation (NIR) materials. The first layer is connected to the signal source and the second to the load, thus forming a series attenuator.

As the signal passes through each layer, it is progressively attenuated until it reaches the desired level of attenuation. Each layer of material is designed to attenuate a specific frequency band and this allows for precise control over the signal level. The attenuation is adjusted by varying the thickness and type of material used in each layer.

HV-AT attenuators type PJ are also able to measure the peak RF voltages and powers by using the reflection coefficient obtained from the signal path. This allows for fast and accurate power monitoring without having to invest in expensive equipment.

Conclusion

HV-AT attenuators type PJ are versatile devices that can be used in a wide variety of high power RF applications. They are designed to provide accurate power measurement and precise control over the signal level. In addition, they offer superior thermal and electrical stability for use in long-term applications.

The working principle of these attenuators make them ideal for use in applications where directivity and peak RF voltages need to be monitored and adjusted precisely. Their stable and reliable performance make them a preferred choice for many professionals.
