4114R-1-105LF

A resistor network, such as the 4114R-1-105LF, is a collection of resistors or other passive elements connected together to achieve a desired electrical function. Such networks typically consist of resistors, which are used to reduce the current flow through the network or divide voltage into the individual components. The 4114R-1-105LF is a unique resistor network based on a Halbleitertechnik CMOS 4049UB/UBC logic integrated circuit chip. It is designed to provide an electrically isolated secondary impedance match for high frequency/high voltage applications.

Application Field

The 4114R-1-105LF is typically used in RF applications such as cellular base stations, aviation telemetry, broadcast communications, and LTE radio systems. It offers high frequency performance and high isolation between the primary and secondary voltage channels. This is especially useful in radio applications, as it allows signals to cross from one side of an antenna to the other with minimal unintended signal interference. In addition, the device can protect against RF radiation and interference by blocking unwanted signals from passing through the isolated circuitry. The 4114R-1-105LF is also ideal for applications such as signal conditioning, current sensing, and thermocouple sensing.

Working Principle

The 4114R-1-105LF resistor network is a passive, open-frame device comprising nine resistors, six transistors, and one diode. Its internal components are organized in such a way as to provide a highly reliable, voltage-independent impedance match between two electrical signals. When the voltage difference between the two signals is within a certain range, the device switches on the transistors, creating a conductive path between the two signals. This path has an impedance matching the ratio of the fixed resistors, allowing the signals to pass through without any measurable loss. In addition, the transistors act to isolate the primary and secondary circuits, preventing undesired feedback or interference from entering either side of the network. As a result of its integrated circuitry, the 4114R-1-105LF is a highly reliable and efficient solution for RF signal applications.

Conclusion

The 4114R-1-105LF is a specialized resistor network designed to provide an electrically isolated secondary impedance match for high frequency/high voltage applications. It is ideal for radio applications, allowing signals to cross from one side of an antenna to the other with minimal interference. In addition, the integrated transistors within the device provide a reliable, voltage-independent impedance match, while simultaneously isolating the primary and secondary circuits from interference. As a result, the 4114R-1-105LF is a high-performance, cost-effective solution for radio applications and other signal conditioning applications.
