ADL8142XCPZN

Overview

The ADL8142XCPZN is a GaAs MMIC low-noise amplifier (LNA) manufactured by Analog Devices Inc. It operates within the 27 GHz to 31 GHz frequency range and utilizes an LFCSP-8 surface-mount package. The device functions with a supply voltage of 2 V and draws a typical current of 25 mA, resulting in a power dissipation of 540 mW. Key electrical specifications include a gain of 29 dB, a noise figure of 1.6 dB, a P1dB compression point of 8.5 dBm, and an OIP3 of 29 dBm. Input return loss ranges from 10.5 dB to 13 dB. It supports an operating temperature range from -40°C to +85°C.

Procurement Notes

Verify the specific suffix 'X' against official Analog Devices documentation to confirm the exact frequency band and pinout configuration, as variations exist within the ADL8142 family. Ensure compatibility with the ADL8142-EVALZ development kit if evaluation is required. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring amplification in the 27–31 GHz E-band spectrum. The choice depends on the need for a single-channel LNA with specific linearity metrics, including an OIP3 of 29 dBm. Consider the LFCSP-8 footprint constraints and the requirement for a 2 V supply rail during system architecture planning.

Part Context

The ADL8142 series comprises GaAs MMIC LNAs optimized for broadband applications. While the base ADL8142 model covers 23–31 GHz, the XCPZN variant specifies operation from 27–31 GHz. This distinction ensures designers match the component to their precise operational bandwidth requirements without over-specifying or under-performing in the target frequency window.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Consult Analog Devices technical support for qualified alternatives that meet identical 27–31 GHz performance criteria.
