ADL8108ACPZN

RF Amplifiers Overview

The ADL8108ACPZN is a highly integrated, 1 GHz to 8 GHz low noise amplifier (LNA) manufactured by Analog Devices Inc. It operates on a single 5V positive supply with a nominal quiescent current of 90mA. The device features an RBIAS drain current adjustment pin and includes on-chip input and output AC coupling capacitors. Typical performance metrics include 20dB gain between 3GHz and 4.5GHz, a 1dB noise figure from 3GHz to 6GHz, and a typical OIP3 of 35.5dBm in the 1GHz to 4.5GHz range. It utilizes a 16-lead LFCSP-WQ (3mm x 3mm) package and supports an extended operating temperature range from -55°C to +125°C.

RF Amplifiers Procurement Notes

Verify the complete part number including the ACPZN suffix to ensure correct packaging and lead-free compliance. Confirm that the specific revision matches the required datasheet version for accurate electrical characteristics. Check RoHS status documentation as specifications may vary by manufacturing batch. Ensure compatibility with the 16-lead LFCSP footprint during PCB layout. Validate supply voltage requirements against system design constraints before procurement.

RF Amplifiers Selection Notes

Select this component when a wideband 1GHz to 8GHz coverage is required within a compact form factor. The integrated enable pin makes it suitable for systems requiring dynamic power control. Consider the 5V supply requirement and 90mA current draw for power budget calculations. The extended temperature range supports operation in harsh environments. Verify that the 50Ω impedance matching aligns with the surrounding RF circuitry design.

RF Amplifiers Part Context

This device belongs to the Analog Devices ADL810x series of low noise amplifiers. It shares functional similarities with other LNAs in the portfolio but is distinct in its specific frequency range and integration level. The ADL8108 focuses on the 1-8GHz band, whereas other models may target lower or higher frequencies. It represents a solution for high-performance RF front-end designs requiring minimal external components.

RF Amplifiers Replacement Considerations

Direct substitutes are not explicitly confirmed in public documentation. Evaluate alternatives based on frequency range, gain, and noise figure specifications. Ensure any replacement maintains the 16-lead LFCSP package for mechanical compatibility. Verify that substitute devices support similar enable logic and biasing requirements.
