ADL8143ACPZN-R7-CSL

RF Amplifiers Overview

The ADL8143ACPZN-R7-CSL is a low noise amplifier (LNA) from Analog Devices Inc. designed for satellite communications applications within the 8 GHz to 14 GHz frequency range. It operates on a single positive supply voltage ranging from 1.2 V to 3.5 V, with a nominal quiescent current of 35 mA. The device provides a typical gain of 28.5 dB and achieves a noise figure of 1 dB. Key performance metrics include an output power at 1 dB compression (P1dB) of 7.5 dBm and a third-order intercept point (OIP3) of 19.5 dBm. It features an input return loss of 11 dB and dissipates up to 950 mW of power. The component is housed in an LFCSP-8 package and supports surface mount installation.

RF Amplifiers Procurement Notes

Verify the specific suffix -CSL against official Analog Devices documentation to confirm availability status and any distinct manufacturing or testing variations compared to standard commercial grades. Ensure compatibility with the required operating temperature range of -55°C to +125°C for your specific application environment before finalizing procurement decisions.

RF Amplifiers Selection Notes

Select this component when designing systems requiring high linearity and low noise in the 8-14 GHz band. Consider the 35 mA supply current and 950 mW power dissipation for thermal management. The LFCSP-8 package requires appropriate PCB layout techniques for exposed pad grounding to ensure optimal RF performance and thermal reliability.

RF Amplifiers Part Context

This part belongs to the ADL8143 series of low noise amplifiers. It is functionally related to the ADL8142, which covers the 23-31 GHz range, but differs significantly in frequency operation and supply requirements. The ADL8143 is distinct from video amplifiers like the AD8143, serving purely RF microwave functions.
