LTC5582IDD

RF Detectors Overview

The LTC5582IDD is a wideband RMS power detector designed for frequencies ranging from 40 MHz to 10 GHz. It provides accurate power measurement across a linear dynamic range of up to 57 dB, handling input signals from -57 dBm to +2 dBm. The device converts RF power into a DC voltage with high precision, maintaining an accuracy of ±0.5 dB typical over temperature. It operates on a single 3.3 V supply with a current consumption of 41.6 mA. The component is housed in a compact 10-lead 3 mm × 3 mm DFN package.

RF Detectors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and tape/reel specifications. Ensure the procurement channel sources genuine components to guarantee the specified ±0.5 dB accuracy and frequency performance. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm availability status and lead times prior to ordering.

RF Detectors Selection Notes

Select this component when precise RMS power detection is required across a broad frequency spectrum up to 10 GHz. It is suitable for applications demanding low linear error and fast response times within a small footprint. Consider the 3.3 V supply requirement and 41.6 mA current draw during power budgeting. Evaluate the need for differential versus single-ended inputs based on the source impedance and layout constraints of the target RF circuit design.
