ADL5545ARKZ-R7

RF Amplifiers Overview

The ADL5545ARKZ-R7 is a single-ended RF/IF gain block amplifier from Analog Devices Inc., designed for broadband operation across the 30 MHz to 6 GHz frequency range. It features a typical gain of 24.1 dB and a noise figure of 2.9 dB at a test frequency of 900 MHz. The device delivers an output power at 1 dB compression (P1dB) of 18.1 dBm and offers an output third-order intercept point (OIP3) of 36.4 dBm. It operates on a supply voltage between 4.75 V and 5.25 V, drawing a supply current of 56 mA. The component is housed in a surface-mount SOT-89-3 package.

RF Amplifiers Procurement Notes

Verify the specific suffix 'R7' corresponds to the tape and reel packaging configuration required for automated assembly processes. Confirm that the SOT-89-3 footprint matches the design board specifications. Ensure compatibility with the 4.75V to 5.25V supply rail constraints during system validation. Cross-reference the manufacturer datasheet for thermal dissipation requirements relative to the intended enclosure environment.

RF Amplifiers Selection Notes

Select this component when a wide bandwidth covering 30 MHz to 6 GHz is necessary within a single-stage amplifier topology. Consider the 24.1 dB gain level against system link budget requirements to determine if additional amplification stages are needed. Evaluate the 2.9 dB noise figure impact on overall system sensitivity, particularly for weak signal reception scenarios. Assess the 18.1 dBm P1dB limit to ensure linear operation under maximum expected input power conditions without distortion.

RF Amplifiers Part Context

This part belongs to the ADL5545 series of RF/IF gain blocks manufactured by Analog Devices Inc. The series is characterized by its ability to provide consistent performance across a broad spectrum, making it distinct from narrowband amplifiers. The ARKZ-R7 designation indicates the specific commercial grade variant with RoHS compliance and reel packaging, differentiating it from evaluation boards or bulk-packaged alternatives.

RF Amplifiers Replacement Considerations

Direct substitutes include other Analog Devices gain blocks such as the ADL5535ARKZ-R7, though frequency ranges and gain specifications differ significantly. Verify pinout compatibility and thermal characteristics before substituting with components from other manufacturers. Ensure that any alternative device meets the same 30 MHz to 6 GHz operational bandwidth and SOT-89-3 package constraints.
