LMH2120UM/NOPB

RF Detectors Overview

The LMH2120UM/NOPB is a linear root-mean-square (RMS) power detector designed for accurate measurement of modulated RF signals with high peak-to-average ratios. It operates across a frequency range of 50 MHz to 6 GHz, supporting multi-band applications including LTE and cellular standards. The device provides a 40 dB dynamic input range from -35 dBm to +5 dBm with an accuracy of ±0.5 dB. It requires a single 2.7 V to 5.5 V supply and draws approximately 2.9 mA of supply current. Packaged in a compact 6-pin DSBGA format, it facilitates surface-mount integration into RF front-end modules.

RF Detectors Feature Summary

• Linear RMS detection capability ensures accurate power measurement for complex modulated signals with large peak-to-average ratios.
• Wide operational frequency bandwidth supports multi-band wireless communication standards from 50 MHz to 6 GHz.
• High measurement accuracy of ±0.5 dB over a 40 dB dynamic input range simplifies system calibration requirements.

RF Detectors Applications

• Power monitoring in LTE cellular handsets
• RF signal measurement in W-CDMA base stations
• Transmitter power control in GSM and EDGE devices

RF Detectors Procurement Notes

Verify the specific suffix NOPB confirms lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the package designation UM corresponds to the 6-pin DSBGA form factor required for your PCB layout. Ensure the operating voltage range aligns with your system's power rail specifications before finalizing procurement orders.

RF Detectors Selection Notes

Select this component when precise RMS power measurement is required for wideband or multi-standard RF signals. The device is suitable for applications demanding high linearity and accuracy across a broad frequency spectrum. Consider the low supply current and small package size for space-constrained portable electronics and dense RF module designs.
