DEA105425BT-1293A1

RF filters are components which are designed to allow low frequency signals to pass through but block higher frequency signals. This is typically necessary in communications systems, where unwanted signals must be filtered out before signals of the desired frequency can be accurately received and processed. The DEA105425BT-1293A1 is a ceramic filter which is commonly used in RF filtering applications.

The DEA105425BT-1293A1 is a miniature ceramic filter which has a passband of 915MHz, a center frequency of 915MHz, and a bandwidth of 40MHz. The filter offers an insertion loss of less than 1.2dB, while also providing a noise rejection of more than 45dB from DC to 1700MHz. Additionally, the filter has a return loss of more than 15dB from DC to 700MHz.

The DEA105425BT-1293A1 filter can be used in a variety of applications, including interference cancelling systems and wireless communication systems. The filter is ideal for use in radio communications where it can be used to reduce interference from other devices. For instance, the filter can be used to reduce the impact of unwanted signals in an interference cancellation system, allowing the desired signal to be better processed.

The working principle of the DEA105425BT-1293A1 is simple. The filter is composed of a dielectric material with interspersed conductive plates. When a signal is sent through the filter, the conductive plates act as capacitors, allowing low frequency signals to pass through while blocking high frequency signals. This is due to the property of capacitors to block the passage of higher frequency signals.

The DEA105425BT-1293A1 filter offers excellent performance in reducing unwanted interference. It has a wide passband and is capable of providing a low noise rejection rate, allowing it to be used in a variety of RF filtering applications. Additionally, the filter is small in size and lightweight, making it ideal for use in portable and wearable electronics.
