LMV225SDX/NOPB

RF Detectors Overview

The LMV225SDX/NOPB is a high-performance, low-power logarithmic RF detector manufactured by Texas Instruments. It operates within a frequency range of 450 MHz to 2 GHz and supports a supply voltage of 2.7 V to 5 V. The device features a single configuration with an accuracy of ±1 dB and a dynamic range of 30 dB. It consumes 8 mA of supply current and functions between -40°C and +85°C. The component is housed in a 6-pin WSON package with an exposed pad, designed for surface mount installation.

RF Detectors Feature Summary

• Optimized for low DC power consumption in battery-operated wireless systems
• Integrated design eliminates external components for simplified circuit implementation

RF Detectors Applications

• CDMA and CDMA2000 cellular base stations and handsets
• W-CDMA and GSM/GPRS mobile communication devices
• EDGE and TDMA wireless infrastructure equipment
• RF power amplifier bias control loops
• Automatic gain control (AGC) circuits in transceivers

RF Detectors Procurement Notes

Verify the specific suffix 'SDX' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 'NOPB' designation indicates lead-free compliance and RoHS standards as per manufacturer specifications. Ensure the 6-pin WSON footprint matches the target PCB layout dimensions and thermal requirements before finalizing procurement orders.

RF Detectors Selection Notes

Select this component when a single-channel logarithmic detector is needed for frequencies up to 2 GHz. Consider the ±1 dB accuracy and 30 dB dynamic range for precise power monitoring applications. Evaluate the 8 mA supply current against system power budgets. Choose this part over alternatives if the 6-pin WSON package offers the necessary space constraints and thermal dissipation capabilities for the design.

RF Detectors Part Context

The LMV225SDX/NOPB belongs to the LMV225 family of RF power detectors from Texas Instruments. This series includes variants like the LMV225TLX and LMV225URX, which share similar functional characteristics but differ in package types such as DSBGA or micro SMD. The SDX variant specifically utilizes a WSON package, distinguishing it within the product line while maintaining compatibility with standard CDMA and WCDMA application requirements.
