RF Diplexers

A diplexer is a type of filter that splits or combines a single radio frequency signal, often at the same time. It is typically used to combine two independent channels on the same antenna or split a single channel into two separate outputs. RF diplexers are commonly used to separate and combine radio signals, such as those used in cellular networks, satellite communication systems, aviation communication systems and radio broadcasting systems. One of the most common types of RF diplexers is the B39142B8560P810S5, which is utilized in a range of applications.

Application Field

The B39142B8560P810S5 RF diplexer is designed for use in mobile communication systems, such as 3G/4G/5G cellular networks, to separate and combine signal from multiple antennas. It is particularly useful in systems that require multiple antenna structures to be combined onto a single device, such as a base station or access point. This diplexer also has applications in radio broadcast systems, where it is used to separate and combine AM and FM channels. It can also be used in land mobile radio, space communication and amateur radio applications, as well as a range of other applications.

Working Principle

The B39142B8560P810S5 is an RF diplexer with two ports that separate and combine radio signals. It can be used to separate or combine frequencies from 600MHz to 2GHz, with a typical band pass of ±2MHz and isolation of 40dB. This diplexer features an inter-modulation figure (IMD) of -50dBc and a voltage standing wave ratio (VSWR) of 1.5. Its attenuation is more than 0.2dB over the whole band.

This RF diplexer works by splitting the input signal into two and diverting each frequency to its own output, or combining two separate signals into one output. This is done using two sections of cavities mounted on an inert material, which are used to direct the frequencies into the correct output. This electromagnetic process reduces any interference or noise and ensures the frequencies are well-balanced. The B39142B8560P810S5 also has an excellent filter rejection that is able to maintain a good low noise figure.

Conclusion

The B39142B8560P810S5 RF diplexer is a versatile device suitable for a wide range of applications. Its low IMD, low noise figure and excellent filter rejection makes it ideal for separating and combining frequencies from 600MHz to 2GHz. It is especially useful for combining multiple antenna structures onto a single device, and is ideal for applications such as cellular networks, radio broadcast systems, land mobile radio, space communication and amateur radio.
