MAX4002EBL-T

RF Detectors Overview

The MAX4002EBL-T is a low-cost, low-power logarithmic amplifier designed for RF power detection in the 100MHz to 2.5GHz frequency range. It features a typical dynamic range of 45dB and operates on a single supply voltage from 2.7V to 5.5V. The device provides a linear-in-dB response with a fast response time of 70ns for a 10dB step. It includes an output sourcing capability of 10mA and consumes only 17mW at 3V typically. The input range spans from -30dBm to +15dBm in a 50Ω system. It is available in an 8-bump UCSP package.

RF Detectors Feature Summary

• Complete RF-detecting power amplifier controller functionality
• Temperature stable linear-in-dB response across the operating band
• Fast transient response suitable for rapid power control loops
• Low power consumption with dedicated shutdown mode

RF Detectors Applications

• Cellular handset power amplifier control
• Transmitter power measurement and control
• Transmit Signal Strength Indicator (TSSI) for wireless terminal devices
• Received Signal Strength Indicator (RSSI) for fiber modules

RF Detectors Procurement Notes

Verify the suffix 'T' indicates tape and reel packaging when ordering. Confirm the 'E' grade specifies the extended temperature range of -40°C to +85°C. Ensure the '+T' designation aligns with lead-free and RoHS compliance requirements if mandated by your project specifications. Cross-reference the specific lot date code against your manufacturing timeline constraints.

RF Detectors Selection Notes

Select this component when a 45dB dynamic range and 2.5GHz upper frequency limit are required for PA control. Choose over MAX4000 or MAX4001 variants specifically because the -30dBm to +15dBm input range matches your signal levels. Consider the UCSP-8 package for space-constrained mobile designs. Verify that the 10mA output drive capability meets the load requirements of your downstream control circuitry.

RF Detectors Part Context

This part belongs to the MAX4000 family of log amps, which share similar architectural features but differ in input ranges. The MAX4002 variant is distinguished by its higher input power tolerance compared to the MAX4000. It serves as a key component in RF front-end modules for cellular communications, enabling precise power management in handsets and base stations.

RF Detectors Replacement Considerations

Direct functional substitutes within the same family include the MAX4000 and MAX4001, though their input ranges differ. For pin-compatible alternatives, verify datasheets for other Maxim Integrated log amplifiers covering the 100MHz-2.5GHz range. Ensure any replacement maintains the 45dB dynamic range and UCSP-8 footprint compatibility.
