ADL8120ACPZN

RF Amplifiers Overview

The ADL8120ACPZN is an ultra-wideband low noise amplifier (LNA) from Analog Devices Inc., designed for operation across a frequency range of 30 kHz to 20 GHz. It features a typical gain of 15 dB and a noise figure of 2.3 dB, powered by a 3.3 V supply with a current draw of 55 mA. The device is housed in an 8-LFCSP package and offers an input return loss of 8 dB and an OIP3 of 26.5 dBm. It supports a maximum power dissipation of 900 mW and operates within a temperature range of -55°C to +125°C.

RF Amplifiers Feature Summary

• Ultra-wideband coverage extending from 30 kHz to 20 GHz for versatile signal processing
• Integrated low noise amplification with high linearity performance
• Compact surface-mount packaging suitable for dense circuit layouts

RF Amplifiers Applications

• Radar systems requiring wideband signal detection
• Electronic warfare applications involving spectrum analysis
• Test and measurement equipment for RF characterization

RF Amplifiers Procurement Notes

Verify the specific suffix requirements when ordering, as the ADL8120ACPZN-R7 variant indicates reel packaging while the base part number may imply tube or other formats. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as specifications can vary by production batch. Ensure that the operating voltage and current parameters align with your system design before finalizing procurement decisions.

RF Amplifiers Selection Notes

Select this component when designing circuits that demand exceptional bandwidth spanning from sub-Hertz frequencies up to millimeter-wave ranges. The low noise figure makes it suitable for sensitive receiver front-ends where signal integrity is critical. Consider the thermal management capabilities given the 900 mW power dissipation rating and the extended temperature range for harsh environment deployments.

RF Amplifiers Part Context

This LNA belongs to the ADL8120 series, which focuses on ultra-wideband performance. It complements other Analog Devices RF solutions like the ADL8124, which offers dual-channel functionality but lacks the ultra-low frequency start point. The ADL8120 is distinct in its ability to handle DC-coupled signals alongside high-frequency RF, providing a unique solution for broadband instrumentation.

RF Amplifiers Replacement Considerations

The ADL8120ACPZN-R7 is a direct packaging variant of this component. For dual-channel requirements, the ADL8124ACPZN serves as a functional alternative within the same family, though it operates from 1 GHz rather than 30 kHz. No other cross-model substitutes are confirmed in public documentation.
