ZFL-500LN+

Overview

The ZFL-500LN+ is a low noise linear amplifier manufactured by Mini-Circuits, designed for operation within the frequency range of 100 kHz to 500 MHz. It provides a typical gain of 24 dB with a noise figure of 2.9 dB. The device operates on a +15 V DC supply with a current consumption of 60 mA. Key performance metrics include a P1dB compression point of 5 dBm and an OIP3 of 17 dBm. It features SMA connectors and is housed in a Y460 package, suitable for screw mounting.

Feature Summary

• Provides high linearity with a typical output third-order intercept point (OIP3) of 17 dBm
• Maintains a very low noise figure of 2.9 dB for sensitive signal reception
• Features good voltage standing wave ratio (VSWR) of 1.5:1 for efficient power transfer
• Operates reliably across a temperature range from -20°C to +71°C

Applications

• UHF and VHF receiver front ends
• Test and measurement instrumentation
• Wireless communication systems requiring low noise amplification

Procurement Notes

Verify the specific suffix designation to ensure compatibility with required connector types and mounting styles. Confirm that the operating voltage and current specifications align with the system power budget. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the Y460 package dimensions fit the designated chassis or PCB layout constraints before ordering.

Selection Notes

Select this component when a wide bandwidth up to 500 MHz is required alongside low noise performance. Compare the 24 dB gain against system link budget requirements to determine if additional amplification stages are necessary. Consider the 50-ohm impedance matching for seamless integration into standard RF transmission lines. Evaluate the thermal management needs given the operating temperature limits and power dissipation characteristics.

Part Context

This model belongs to the ZFL series of low noise amplifiers from Mini-Circuits. The series is known for providing consistent performance across various frequency bands. The ZFL-500LN+ specifically targets applications below 500 MHz, distinguishing it from higher-frequency variants like the ZFL-1000LN+. It utilizes silicon technology for robust operation in commercial and industrial environments.
