RF accessories are a wide ranging product category that includes a variety of products essential to many different types of communications systems. One such product is the MB195SMBI, which is used in wireless communication systems to switch between multiple radiofrequency sources. In this article, we will explore the MB195SMBI application field and its working principle.

MB195SMBI Application Field

The MB195SMBI is a bypass switch unit designed for use in wireless communications systems operating in the microwave frequency range. It is a dual-channel bidirectional switch that is rated for up to 6GHz and has an insertion loss of 0.7dB or less. It has a switching time of less than 1.1s and a linearity of 0.8dB. The MB195SMBI is commonly used in the following applications:

• Wireless communication system upstream/downstream signal switching
• Multi-channel signal receiver switching
• Jamming signal monitoring

Working Principle of MB195SMBI

The MB195SMBI is a two-channel bidirectional switch, meaning it is capable of switching a signal in either direction between two separate signal paths. Its switching speed and linearity are especially important in wireless communication systems, where it is often necessary to switch rapidly between multiple sources and simultaneously detect signal level changes over time. The basic principle of operation is as follows:

• The MB195SMBI has a two-channel input and two-channel output, with each channel capable of switching a signal in either direction.
• The switch is controlled by a logic pin, which can be connected to a microcontroller or other logic control unit.
• When the logic pin is low, the switch is open and the corresponding signal path is blocked. When the logic pin is high, the switch is closed and the signal can pass through.
• The MB195SMBI is also equipped with an RF input attenuator, which can be used to reduce the signal level before it is switched. This reduces channel-change noise and improves linearity.

Conclusion

The MB195SMBI is a dual-channel bidirectional switch used in wireless communication systems. It has a switching time of less than 1.1s and a linearity of 0.8dB, making it suitable for applications that require rapid switching between two or more signal sources. The switch is controlled by a logic pin, which can be connected to a microcontroller or other logic control unit. Additionally, it is equipped with an RF input attenuator to reduce channel-change noise and improve linearity.
