RF filters are specialized filters used to reduce or block unwanted radio signals, allowing only desired signals to pass. By suppressing unwanted interference, they help to create reliable communications in wireless technologies. The DEA 161910LT-5003C1 is an RF filter with low insertion loss and in-band rejection up to 200dB. This article will discuss the application field and working principle of this filter.

Application field

The DEA 161910LT-5003C1 is a high-performance, low-cost filter. It is designed for use in cellular base stations, handset systems, mobile radios, and other radio frequency (RF) applications. It is a wideband filter with a frequency range of 36.9 - 40.5 GHz. This makes it suitable for use in applications such as point-to-point and point-to-multipoint links, subscriber stations, and satellite communications.

The filter is capable of handling input power up to +20 dBm, with a low insertion loss of 1.5 dB. It is designed to provide excellent out-of-band rejection with a rejection rating of 200dB, meaning that it will effectively reject any spurious signals that may be present in the system. The filter also has a low profile, making it easy to install and maintain.

Working principle

The working principle of the DEA 161910LT-5003C1 filter is based on the use of a multi-cavity filter structure. This filter is a high-performance design that utilizes a combination of two-pole, four-pole, and eight-pole filter sections. This ensures that the filter will have excellent out-of-band rejection and low insertion loss. The two-pole filter sections provide the passband and out-of-band rejection, while the four-pole and eight-pole filter sections provide additional out-of-band rejection.

The filter is designed to pass signals in the frequency range of 36.9 GHz to 40.5 GHz. It is able to do this by using a combination of two-pole, four-pole, and eight-pole filter sections within the filter. This ensures that signals in the pass band are allowed to pass, while signals outside the passband are blocked. The two-pole filter section provides the passband filtering, while the four-pole and eight-pole sections provide out-of-band rejection.

The filter also provides excellent in-band isolation, meaning that signals in the pass band will not interfere with one another. This is accomplished by using a combination of four-pole and eight-pole filter sections that reject signals outside the passband. This ensures that signals in the pass band have no interference from signals outside the pass band.This helps to reduce noise and ensure reliable communication.

Conclusion

The DEA 161910LT-5003C1 filter is a high-performance, low-cost filter designed for use in cellular base stations, handset systems, mobile radios, and other radio frequency (RF) applications. It is a wideband filter with a frequency range of 36.9 - 40.5 GHz. The filter is capable of handling input power up to +20 dBm, with a low insertion loss of 1.5 dB and excellent out-of-band rejection of 200dB. The filter utilizes a multi-cavity filter structure, with two-pole, four-pole, and eight-pole filter sections. This ensures excellent in-band isolation, low insertion loss and high out-of-band rejection, resulting in reliable performance. The DEA 161910LT-5003C1 filter is an ideal high-performance filter solution for radio frequency applications.
