LT5538IDD#PBF

RF Detectors Overview

The LT5538IDD#PBF is a monolithic logarithmic RF power detector manufactured by Analog Devices Inc. It operates within a frequency range of 40MHz to 3.8GHz and measures RF signals over a dynamic range from -75dBm to 10dBm. The device provides a typical linear dynamic range of 75dB with ±1dB linearity error at 25°C. It features a single-ended RF input and is housed in an 8-pin WDFN package with an exposed pad.

RF Detectors Feature Summary

• Monolithic logarithmic detection architecture for wideband RF applications
• Single-ended RF input configuration simplifies circuit design
• Exceptional measurement accuracy maintained across temperature variations

RF Detectors Applications

• RF power monitoring in wireless communication systems
• Signal strength indication in receiver front-ends
• Automatic gain control loop feedback elements

RF Detectors Procurement Notes

Verify the specific ordering suffix, such as #PBF or #TRPBF, against project requirements to ensure correct packaging format. Confirm that the component meets all applicable automotive or industrial qualification standards if required by the end application. Cross-reference the manufacturer datasheet for exact pinout and thermal specifications before finalizing procurement orders.

RF Detectors Selection Notes

Select this component when a wide dynamic range and high accuracy are required for frequencies up to 3.8GHz. The single-ended input topology reduces component count compared to differential alternatives. Ensure the operating temperature range aligns with the system environment, as accuracy specifications are typically defined at standard ambient temperatures.

RF Detectors Part Context

This part belongs to the LT5538 family of RF power detectors designed for general-purpose signal measurement. Variants include tube-packed (#PBF) and tape-and-reel (#TRPBF) options. The series supports applications requiring reliable logarithmic response over broad signal levels without external calibration.

RF Detectors Replacement Considerations

LT5538IDD-PBF and LT5538IDD-TRPBF are confirmed equivalent variants within the same product family.
