ZRL-3500+

Overview

The Mini-Circuits ZRL-3500+ is a connectorized SMA low noise linear amplifier operating within the 700 MHz to 3500 MHz frequency range. It provides a nominal gain of 21 dB with a typical noise figure of 2.4 dB. The device supports an output power of 24 dBm and requires a 12 VDC supply, drawing approximately 460 mA. Designed for 50Ω systems, this medium-power RF amplifier features SMA connectors for integration into signal chains requiring amplification across cellular and wireless bands.

Feature Summary

• Low noise linear amplification in the 700 MHz to 3500 MHz range
• SMA connectorized interface for 50Ω system integration
• Medium power output capability suitable for signal chain boosting

Applications

• Cellular base station front-end modules
• GPS and GNSS receiver signal conditioning
• WLAN infrastructure equipment
• Test and measurement instrumentation

Procurement Notes

Verify the exact part number suffix against the manufacturer's current datasheet to ensure compatibility with specific voltage or connector requirements. Confirm that the 12 VDC supply specifications align with your system design before procurement. Cross-reference the impedance rating to ensure it matches your 50Ω environment. Check for any recent revisions in the official documentation that may affect performance parameters or pinout configurations.

Selection Notes

Select the ZRL-3500+ when a dedicated low-noise stage is required between 700 MHz and 3.5 GHz. Its 2.4 dB noise figure makes it suitable for sensitive receiver applications where signal integrity is critical. Consider its 24 dBm output power for driving subsequent stages without saturation. Ensure the SMA interface fits your board layout constraints and that the 12 VDC power budget accommodates the 460 mA current draw.

Part Context

This component belongs to Mini-Circuits' ZRL series of connectorized low noise amplifiers. These devices are designed for general-purpose RF applications requiring reliable amplification across wide bandwidths. The ZRL-3500+ specifically targets the sub-4 GHz spectrum, bridging gaps between lower frequency IF stages and higher frequency upconverters in communication systems.

Replacement Considerations

Consult Mini-Circuits official substitution guides for direct replacements. Verify that alternative models maintain the same SMA interface, 12 VDC operation, and 50Ω impedance. Ensure the substitute meets or exceeds the 21 dB gain and 2.4 dB noise figure requirements for your specific application.
