LTC5533EDE#PBF

RF Detectors Overview

The LTC5533EDE#PBF is a dual-channel RF power detector designed for applications operating within the 300 MHz to 11 GHz frequency range. It features two independent temperature-compensated Schottky diode peak detectors with buffered outputs providing a gain of 2x. The device supports an input power range from -32 dBm to 12 dBm and operates on a supply voltage between 2.7 V and 6 V. Key electrical parameters include ±1 dB accuracy, channel-to-channel isolation of 45 dB at 2 GHz, and low current consumption of less than 500 µA per channel. It is housed in a 4 mm × 3 mm DFN package.

RF Detectors Procurement Notes

Verify that the ordering suffix #PBF indicates lead-free and RoHS compliance status as specified by Analog Devices. Confirm the package marking matches the DE-12 DFN identifier. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for any specific handling requirements related to the exposed pad thermal termination during assembly.

RF Detectors Selection Notes

Select this component when dual-channel detection is required across ultra-wideband frequencies up to 11 GHz. It is suitable for designs needing high channel isolation and precise power measurement with ±1 dB accuracy. Consider the low supply current requirement if power efficiency is critical. Ensure the system voltage falls within the 2.7 V to 6 V range and that the input power levels remain between -32 dBm and 12 dBm.

RF Detectors Part Context

The LTC5533 belongs to Analog Devices' family of precision RF power detectors. It integrates two complete detector channels into a compact footprint, eliminating the need for external buffering or complex calibration circuits. The device addresses the need for accurate power monitoring in multi-standard wireless communication equipment where space and power constraints are significant.
