ZFL-500LNB+

Overview

The ZFL-500LNB+ is a low noise linear amplifier manufactured by Mini-Circuits, designed for operation within the frequency range of 0.1 MHz to 500 MHz. It features a nominal impedance of 50 ohms and utilizes SMA connectors for signal interfacing. The device operates on a DC voltage supply with a maximum rating of +17V. The specified operating temperature range extends from -20°C to 71°C, while storage capabilities span from -55°C to 100°C. This component is categorized as a connectorized RF amplifier suitable for UHF and VHF applications.

Feature Summary

• Low noise linear amplification characteristics optimized for sensitive signal reception
• Wideband operational coverage spanning from 0.1 MHz to 500 MHz
• Integrated SMA connectors for direct circuit board or cable interface

Applications

• UHF and VHF signal processing systems
• RF receiver front-end stages requiring low noise performance
• General purpose linear amplification in microwave circuits

Procurement Notes

Verify that the specific suffix 'B' denotes the BNC connector variant if required, as standard models may utilize SMA. Confirm the exact datasheet revision (e.g., REV. F) matches the electrical specifications needed for your design. Ensure the DC supply voltage does not exceed the +17V maximum limit to prevent device damage. Check thermal requirements against the -20°C to 71°C operating range for your specific environment.

Selection Notes

Select this model when a wideband low noise amplifier is needed below 500 MHz. Consider the physical connector type; the ZFL-500LNB+ specifically indicates BNC connectivity, whereas other variants like ZFL-500LN+ use SMA. Evaluate the power supply constraints against the +17V maximum rating. Ensure the application environment stays within the specified operating temperature limits to maintain performance stability.

Part Context

This component belongs to the ZFL series of low noise amplifiers from Mini-Circuits. The series offers various frequency ranges and connector options. The ZFL-500LNB+ is a specific variant tailored for lower frequency operations up to 500 MHz with BNC interfaces. It serves as a building block for RF systems requiring gain and noise figure optimization in the VHF/UHF bands.

Replacement Considerations

The ZFL-500LN+ is a confirmed substitute part number within the same product family, offering similar electrical performance but utilizing SMA connectors instead of BNC. Verify connector compatibility before substitution. Other ZFL series models may offer different frequency ranges.
