LTC5582IDD#PBF

RF Detectors Overview

The LTC5582IDD#PBF is a single-channel RMS power detector manufactured by Analog Devices Inc. It operates within a frequency range of 40 MHz to 10 GHz and provides a dynamic range of 57 dB, covering an input power span from -57 dBm to +2 dBm. The device maintains an accuracy of ±0.5 dB across its operating range. It functions on a single supply voltage between 3.1 V and 3.5 V, drawing a typical supply current of 41.6 mA. The component is housed in a 10-lead WDFN package measuring 3 mm by 3 mm with an exposed pad for thermal management.

RF Detectors Feature Summary

• Provides true RMS detection capability for accurate power measurement across wide bandwidths
• Delivers high linearity with specified accuracy over a broad dynamic range
• Supports direct interfacing with ADCs via integrated low-pass filtering
• Operates efficiently on a single low-voltage power supply

RF Detectors Applications

• CDMA base station receiver monitoring
• LTE signal power measurement
• W-CDMA network infrastructure testing
• WiMAX system calibration

RF Detectors Procurement Notes

Verify the specific suffix designation when ordering, as variants such as TRPBF indicate tape-and-reel packaging while PBF denotes tube packaging. Confirm that the required frequency coverage aligns with the 40 MHz to 10 GHz specification. Ensure the design accommodates the 3.1 V to 3.5 V supply requirement and the thermal characteristics associated with the exposed pad DFN package.

RF Detectors Selection Notes

Select this component for applications requiring precise RMS power measurement in wireless communication systems. It is suitable for designs needing a wide dynamic range without external linearization circuits. Consider the package size constraints and the need for a stable single-supply voltage. Evaluate the compatibility with downstream analog-to-digital converters given the internal filter characteristics.

RF Detectors Part Context

This part belongs to the LTC5582 series of RF detectors designed for high-performance wireless infrastructure. It serves as a critical interface between RF front-end components and baseband processing units. The series supports various packaging options to accommodate different production volumes and thermal requirements within modern communication equipment.

RF Detectors Replacement Considerations

Direct substitutes include the LTC5582HDD#PBF and LTC5582IDD#TRPBF. These alternatives share identical electrical specifications and pinouts but differ in shipping configuration or temperature grade. Verify package compatibility before substitution.
