ADL5726ACPZN-R7

RF Amplifiers Overview

The ADL5726ACPZN-R7 is a dual-channel low-noise amplifier (LNA) from Analog Devices, designed for the 21.2 GHz to 23.6 GHz frequency range. It features a single-ended 50 Ω input impedance and provides a 100 Ω balanced differential output, facilitating direct connection to mixers or ADCs. The device operates within a temperature range of -40°C to +85°C and utilizes Silicon Germanium (SiGe) technology. Packaged in an 8-lead LFCSP (2x2 mm), it supports applications requiring high linearity and low noise figure in microwave systems.

RF Amplifiers Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm that the received package matches the specified LFCSP-8 form factor and marking codes. Ensure storage conditions comply with moisture sensitivity levels prior to reflow soldering. Cross-reference datasheet revisions to confirm pinout compatibility with existing designs. Validate supply chain documentation against current manufacturing status reports.

RF Amplifiers Selection Notes

Select this component when designing systems operating specifically within the 21.2–23.6 GHz band. Consider its integrated output impedance if minimizing passive components is critical. Evaluate thermal management requirements given the -40°C to +85°C operational window. Compare noise figure and gain specifications against alternative LNAs for link budget calculations. Assess PCB layout constraints associated with the small 2x2 mm footprint.
