RF filters are a class of passive electronic filters typically used in communication systems to filter out or attenuate interfering or unwanted signals while allowing desired signals to pass with minimal distortion. The DEA202450BT-1283A2 is one such RF filter designed to deliver precise signal frequency selection and high performance with built-in shielding for the best possible protection against unwanted interference. This filter features a passband from 20 to 2450 MHz with a typical insertion loss of less than 0.5 dB over this range. Additionally, this device is capable of withstand high power levels, making it suitable for multiple applications and environments.

The DEA202450BT-1283A2 RF filter is commonly applied in numerous applications such as wireless local area networks (WLANs), cellular base station systems, CATV infrastructure, and broadband home networking. It is also commonly used in high-end, narrower-band radar systems to provide a high level of signal isolation without increasing the complexity of the design. With its excellent performance, it is well-suited for various scenarios, including in-building communications, outdoor base station applications, and large-scale civilian and military communications.

The working principle of the DEA202450BT-1283A2 RF filter is based on the selective absorption had by the signal at specific frequencies within the passband. This filter works by using a combline filter technology that allows for precise frequency selection. The filter design consists of a number of parallel-coupled resonators that resonate in the passband frequency, typically over the range of 20-2450 MHz. These resonators serve to absorb energy at specific frequencies, effectively filtering out any signals that are not within the desired frequency range and allowing only desired signals to pass through.

The DEA202450BT-1283A2 RF filter also features built-in shielding to further reduce the risk of external interference. The filter is designed using an integrated three-height shielding structure, providing an isolation of more than 80 dB between input and output ports. This ensures that unwanted signals are not able to penetrate the filter and interfere with the desired signal.

In addition, the DEA202450BT-1283A2 RF filter has been tested and verified to withstand high power levels, making it ideal for high power applications. It is designed with high-temperature-resistant construction materials that allow it to work at temperatures up to +85°C. The filter also features robust welding technology to ensure reliable and guaranteed performance in harsh environments.

The DEA202450BT-1283A2 RF filter is a powerful device that provides excellent signal filtering for multiple applications. With its precise frequency selection and high-level of shielding, this device provides an effective means to reduce interference while allowing desired frequencies to pass efficiently. Its robust design also allows it to function reliably in high power and high temperature environments. As such, this filter is an ideal choice for numerous applications from WLANs to radar systems.
