ADL8140ACPZN

RF Amplifiers Overview

The ADL8140ACPZN is a low noise amplifier (LNA) operating from 10 GHz to 18 GHz. It features a typical gain of 27.5 dB and a noise figure of 1 dB within the 12 GHz to 15 GHz range. The device operates on a single 1.5 V supply with a nominal static current of 35 mA, adjustable via an external resistor. Input and output ports are AC-coupled and internally matched to 50 Ω. The component is housed in a 2 mm x 2 mm 8-lead LFCSP package and supports an operating temperature range of −55°C to +125°C.

RF Amplifiers Procurement Notes

Verify the specific suffix (ACPZN) against official Analog Devices documentation to confirm package type and RoHS compliance status. Ensure the ordering part number matches the required temperature rating and lead finish specifications. Cross-reference the datasheet revision date to confirm technical parameters align with current production standards before procurement.

RF Amplifiers Selection Notes

Select this component for high-frequency designs requiring minimal external matching networks due to internal 50 Ω impedance matching. Consider the adjustable bias current feature for power optimization in battery-constrained systems. Verify that the 1.5 V supply voltage aligns with system power rails and that the thermal performance meets requirements for the specified operating temperature range.
