RF Diplexers: D5DA881M5K2E4-Z Application Field and Working Principle

RF diplexers are devices used in RF communications and are designed to separate or combine signals from various frequency bands. The D5DA881M5K2E4-Z RF diplexer, developed by Avago Technologies, is an example of a multi-channel diplexer used in today’s radio communications systems.

What is a Diplexer?

A diplexer is a device that is typically used in radio communication systems to combine or separate two frequency bands. This is done to allow the system to share one antenna for two different communications. It is also used to separate signals on multiple bands for increased signal clarity.Typically, a diplexer contains two filters. The first filter is a low pass filter which is used to separate the low frequency signals from the high frequency signals. The second filter is a high pass filter which is used to separate the high frequency signals from the low frequency signals.

D5DA881M5K2E4-Z RF Diplexer

Avago Technologies’ D5DA881M5K2E4-Z RF diplexer is an 8-channel diplexer designed to separate and combine signals for a variety of applications, such as WLAN, WiMAX, and WiBro. This diplexer is available in both single-pole triple throw (SP3T) and dual-pole quad throw (SP4T) configurations.The D5DA881M5K2E4-Z diplexer can handle a wide range of frequencies from 3.3-3.8 GHz and 4.9-5.9 GHz. It has a typical insertion loss of 2dB and provides up to 20dB of isolation between the high frequency and low frequency ports.

Working Principle

The working principle of the D5DA881M5K2E4-Z RF diplexer is fairly simple. It uses two filters to separate and combine signals of different frequencies.The signals enter the diplexer where they are directed through the low pass filter. This filter passes low frequency signals and blocks high frequency signals. The low frequency signals then pass through the high pass filter which passes high frequency signals and blocks low frequency signals.The combined signals are then directed to the output port. This output port can be connected to a single antenna, allowing it to be used for both low frequency and high frequency signals.

Applications

The Avago D5DA881M5K2E4-Z RF diplexer has a variety of applications. It can be used in WLAN systems, WiMAX systems, and WiBro systems for combining and separating signals of different frequencies.It can also be used in cellular systems, GPS systems, and other radio communication systems. The diplexer can be used to improve signal clarity and reduce interference between signals of different frequencies.

Conclusion

The Avago D5DA881M5K2E4-Z RF diplexer is a multi-channel diplexer designed to separate and combine signals of different frequencies. It has a wide range of application, including WLAN systems, WiMAX systems, and WiBro systems. It provides high levels of signal clarity and isolation between the high frequency and low frequency ports. By using the two filters, the diplexer can be used to separate and combine radio signals for a variety of applications.
