Product details
Overview
LMH2110TMX/NOPB from Texas Instruments is an 8-GHz logarithmic RMS power detector optimized for accurate RF power measurement of high-PAR modulated signals (e.g., W-CDMA, LTE) in cellular front-end modules. It delivers ±0.5 dB log conformance over 45 dB dynamic range (–40 dBm to +5 dBm), operates from 2.7 V to 5 V, and features shutdown control via EN pin with high-impedance output during sleep.
For engineers reviewing the LMH2110TMX/NOPB datasheet, LMH2110TMX/NOPB pinout, LMH2110TMX/NOPB application, or LMH2110TMX/NOPB equivalent, key selection criteria include its RMS-based modulation independence, temperature-insensitive slope (±0.25 dB), 6-bump DSBGA package footprint, and compatibility with directional couplers or resistive dividers in multi-band RF power control loops.
Technical Context
The LMH2110TMX/NOPB implements a true RMS detection architecture using internal exponential conversion and precision analog processing, ensuring modulation-independent response across W-CDMA, LTE, and OFDMA waveforms. Its integrated LDO decouples output accuracy from supply ripple, enabling stable operation under noisy DC conditions.
It supports RF input frequencies from 50 MHz to 8 GHz with frequency-dependent log slope (41.8–47.1 mV/dB) and intercept (–38.6 to –19.9 dBm), calibrated per band. The EN-controlled shutdown reduces supply current to <6.1 µA while placing OUT in high-impedance state to preserve external filter charge.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 50 MHz to 8 GHz - enables single-detector coverage across GSM/EDGE, CDMA, W-CDMA, LTE, and 5G sub-6 GHz bands. |
| Dynamic Range | 45 dB (–40 dBm to +5 dBm) - supports full transmit power monitoring from low-level pilot signals to peak PA output. |
| Log Conformance Error | ±0.5 dB max - ensures direct dBm-to-voltage translation without per-unit calibration in production. |
| Temperature Drift | ±0.25 dB over –40°C to +85°C - eliminates need for thermal compensation circuitry in baseband power control loops. |
| Supply Voltage Range | 2.7 V to 5 V - compatible with both 3.3 V and 5 V system rails, including battery-backed RF sections. |
| Shutdown Current | <6.1 µA at VDD = 4.5 V - minimizes standby power in always-on RF monitoring paths. |
| Turnon Time | 19 µs max - supports fast AGC loop response and burst-mode transmission timing. |
Pinout & Package
LMH2110TMX/NOPB uses a 6-bump DSBGA (YFQ) package measuring 1.27 mm × 0.87 mm with 0.4 mm bump pitch. The ultra-compact footprint supports high-density RF layout adjacent to power amplifiers and couplers.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | VDD | Positive supply input - connects to regulated 2.7–5 V rail; internally powers LDO and core detector. |
| A2 | OUT | Analog output voltage - ground-referenced linear-in-dB voltage (3 mV to 1.96 V) proportional to RF input power. |
| B1 | RFIN | RF input terminal - 50 Ω internally terminated; accepts CW or modulated signals from 50 MHz to 8 GHz. |
| B2, C1 | GND | Power ground - dual ground bumps reduce impedance and improve RF return path integrity. |
| C2 | EN | Logic enable input - HIGH (>1.1 V) activates detector; LOW (<0.6 V) enables shutdown with high-Z OUT. |
Key Features
| Feature | Design Value |
|---|---|
| Logarithmic RMS Response | True RMS detection topology ensures accurate power measurement regardless of signal crest factor or modulation format (W-CDMA, LTE, QAM). |
| Multi-Band Operation | Validated performance from 50 MHz to 8 GHz - eliminates need for band-switched detectors in multi-mode transceivers. |
| Integrated LDO | On-chip low-dropout regulator rejects supply noise up to 56 dB, enabling direct connection to noisy digital or PA supply rails. |
| Shutdown Mode | EN-controlled sleep mode reduces current to <6.1 µA and disables OUT driver - preserves external RC filter charge and saves system power. |
| High Temp Stability | ±0.25 dB total error over –40°C to +85°C - enables uncalibrated operation in outdoor small cells and automotive telematics. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar logarithmic RMS power detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5511ACPZ-R7 | Wider bandwidth (up to 10 GHz), higher supply current (12 mA active), no integrated LDO - requires clean 3.3 V supply. | Better suited for millimeter-wave test equipment; less tolerant of noisy PA supply rails than LMH2110TMX/NOPB. | Select when >8 GHz coverage or superior high-frequency log conformance is required; verify external supply filtering. |
| MAX2016ETE+ | Narrower RF range (40 MHz–2.5 GHz), lower dynamic range (35 dB), integrated temperature compensation - optimized for 2G/3G infrastructure. | Limited to sub-3 GHz bands; not suitable for LTE-A carrier aggregation or 5G NR FR1 deployments. | Choose for cost-sensitive legacy infrastructure where 8 GHz capability is unnecessary and temperature drift must be actively corrected. |
Compared with ADL5511ACPZ-R7 and MAX2016ETE+, the LMH2110TMX/NOPB uniquely balances 8 GHz bandwidth, 45 dB dynamic range, integrated LDO, and ultra-low shutdown current in a 1.27 mm × 0.87 mm DSBGA - making it optimal for space-constrained, multi-band mobile and small-cell RF power control where supply noise and thermal stability are critical.

FAQ
What is the RF input impedance of the LMH2110TMX/NOPB, and is external matching required?
The LMH2110TMX/NOPB features a 50 Ω internally terminated RF input (RFIN) across its full 50 MHz–8 GHz range, as confirmed by impedance plots in the datasheet. No external matching network is needed - the device is designed for direct connection to 50 Ω source impedances such as directional couplers or resistive dividers. This simplifies PCB layout and eliminates tuning complexity in production.
Does the LMH2110TMX/NOPB require calibration for different modulation formats like LTE 64-QAM or W-CDMA Release 8?
No, the LMH2110TMX/NOPB does not require per-modulation calibration. Its true RMS detection architecture provides modulation-independent response, with input-referred variation of only 0.08 dB for W-CDMA and 0.19 dB for LTE under specified power ranges. This enables single-point calibration across all supported waveforms, reducing factory test time and firmware overhead.
How does the LMH2110TMX/NOPB behave during shutdown, and what happens to the OUT pin?
When EN is driven LOW (<0.6 V), the LMH2110TMX/NOPB enters shutdown mode, drawing <6.1 µA supply current. Critically, the OUT pin transitions to high-impedance state - it neither sources nor sinks current - preserving charge on any external RC filter capacitor. This prevents discharge-induced voltage droop and allows fast wake-up without recharging delays.
What is the typical output voltage range of the LMH2110TMX/NOPB, and how does it map to RF input power?
The LMH2110TMX/NOPB outputs a ground-referenced voltage linearly proportional to RF input power in dBm. At RFIN = –40 dBm (50 MHz), VOUT ≈ 3 mV; at RFIN = +5 dBm (50 MHz), VOUT ≈ 1.96 V. The slope is typically 44.3 mV/dB with intercept –38.3 dBm, enabling direct dBm calculation: PdBm = (VOUT – VINT) / KSLOPE.
Can the LMH2110TMX/NOPB operate from a 3.3 V supply, and how does supply voltage affect accuracy?
Yes, the LMH2110TMX/NOPB operates fully across 2.7 V to 5 V. Its integrated LDO ensures supply rejection ratio (PSRR) of 56 dB, meaning output voltage accuracy remains unaffected by supply ripple or droop. Measured log conformance error and slope variation are specified worst-case across the entire supply range - no derating or recalibration is needed when using 3.3 V.
