RF Diplexers are devices that allow signal transmission between two or more antennas with different frequency ranges. They provide a way of selectively separating different signals within the range of frequencies, while at the same time blocking or attenuating signals in other frequency bands. The CER0215B is a typical example of an RF diplexer.

The CER0215B is an integrated RF diplexer designed for use in indoor wireless applications such as wireless access points and base stations. Its working principle is twofold. First, a diplexer includes bandpass filters that separate the desired signal frequencies from all other frequencies. Second, it consists of power dividers and couplers, which divide the input power into two components: one that travels through each of the filters.

The CER0215B is designed to operate in the 2.4-2.5GHz and 4.9-5.8GHz bands. It is a compact device designed for easy installation and use in confined spaces, and offers low insertion loss and high isolation. The device has a power handling capability of 10W per port, making it suitable for high output power applications. The CER0215B also offers good temperature stability, and the ability to withstand extremes of vibration, shock and humidity.

The CER0215B has a wide range of application fields. It is commonly used in 802.11g and 802.11n wireless networks, as well as WLAN access points and base stations. It is also used in Point-to-Point and Point-to-MultiPoint bridges, and WLAN systems requiring high throughput and reliability. Additionally, the CER0215B is suitable for frequencies used in GSM and UMTS networks, and for use in airports and public utilities.

In summary, the CER0215B is an integrated RF diplexer designed for use in indoor wireless applications, with a working principle based on bandpass filters, power dividers and couplers. This device is designed to provide selective signal separation within the 2.4-2.5GHz and 4.9-5.8GHz bands, and is well suited for various wireless communication applications.
