RF Diplexers

RFDIP2012050L7T Application Field and Working Principle

RF diplexers are a type of passive electronic component used to separate the radio frequency (RF) signal into two frequency bands. Generally, diplexers are composed of two or more components, such as filters, amplifiers, mixers, and isolators. RF diplexers are widely used in various applications, including amateur radio, microwave, wireless communication systems, broadcast and telecommunication systems.

RFDIP2012050L7T Application Field

RFDIP2012050L7T is a wideband diplexer with two bands covering 50 MHz-2 GHz and 700 MHz -20GHz, the insertion loss is less than 0.6 dB which can reduce the power loss of the system. It is applicable for mobile bus, base station, UAV system, satellite communication, wireless network and other related fields. It has high linearity, low reflection coefficient and low noise figure, which can guarantee a stable system and prevent interference. In addition, its good out-of-band suppression can suppress the interference signal in the adjacent band, ensuring low interference among systems.

RFDIP2012050L7T Working Principle

RFDIP2012050L7T works by directing different frequencies on individual or multiple channels to different outputs. This is achieved by using low-pass filters, high-pass filters, or both in one device. The low-pass filter passes lower frequencies and attenuates higher frequencies. The high-pass filter passes higher frequencies and attenuates lower frequencies. A band pass filter passes all frequencies within a certain range and attenuates frequencies outside of that range.

In these devices, input signals are separated into two paths and sent through a low-pass filter and a high-pass filter, respectively. The low-pass filter will pass all signals from 0 MHz to the specified cutoff frequency, while the high-pass filter will pass all signals from the specified cutoff frequency to the highest frequency. The output of each is then combined together through a 3dB or 6dB hybrid coupler, and the combined signal is sent to the output.

RFDIP2012050L7T can be used to separate a single input signal into two output signals—one in the 500MHz-2GHz range and the other in the 700MHz-20GHz range. In addition, RFDIP2012050L7T can be used to combine two distinct signals into a single output. This is useful in applications such as combining radio signals from different protocol radios, enabling them to be processed together.

Conclusion

RFDIP2012050L7T is a type of RF diplexer capable of separating or combining radio frequency signals of different ranges. This type of diplexer is used in various wireless communication, broadcast, satellite, and telecommunication applications. The device works by passing signals through low-pass and high-pass filters and combining the resulting signals in a hybrid coupler.
