Product details
Overview
MAX2209EBS+T10 from Maxim Integrated is a wideband RF power detector operating from 800MHz to 2GHz, delivering DC output voltage proportional to RF peak voltage with ±0.5dB residual detection error after room-temperature calibration, -25dBm to 0dBm input range, and single-supply operation from +2.7V to +5V - used in WCDMA/HSDPA/HSUPA handset transmit power control loops.
For engineers reviewing the MAX2209EBS+T10 datasheet, MAX2209EBS+T10 pinout, MAX2209EBS+T10 application, or MAX2209EBS+T10 equivalent, key selection criteria include temperature-stable detection error across -40°C to +85°C, integrated 50Ω RF termination and DC-blocking capacitor, ultra-small 4-bump UCSP™ package (1mm²), and compatibility with directional coupler–based RF sampling in cellular front-end modules.
Technical Context
The MAX2209EBS+T10 implements a bipolar-process RF detector core optimized for envelope detection of modulated signals in 3G/4G cellular bands. Its output voltage scales linearly with log input power (dBm), enabling direct ADC digitization without external compensation circuitry.
It features on-chip 50Ω RF termination at RFIN and internal DC-blocking, eliminating external matching components. The output exhibits repeatable thermal drift behavior across units, supporting factory calibration via lookup table rather than per-unit trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 800MHz to 2000MHz - supports full WCDMA dual-band (836MHz & 1950MHz) and HSDPA/HSUPA uplink/downlink operation. |
| Detection Range | -25dBm to 0dBm - covers typical PA output power levels before antenna switch or coupler insertion loss. |
| Residual Error (Temp) | ±0.5dB at -5dBm, ±1.5dB at -25dBm (TA = -40°C to +85°C) - enables single-point room-temp calibration for <1dB system-level TX power error. |
| Supply Voltage | +2.7V to +5.0V - compatible with standard baseband processor I/O rails and battery-sourced LDOs. |
| Supply Current | 3.6mA to 6mA - low quiescent draw suitable for always-on TX power monitoring in battery-powered handsets. |
| Output Voltage Range | 60mV to 880mV (at -25dBm to -5dBm, 836MHz) - fits within 0–1V ADC input range without scaling amplifiers. |
Pinout & Package
The MAX2209EBS+T10 is housed in a 4-bump, 1mm² wafer-level package (UCSP™) with 0.5mm pitch, designed for high-density RF front-end layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Detector analog output - drives ADC input directly; requires series resistor + shunt capacitor to suppress ripple. |
| A2 | VCC | Single positive supply - must be bypassed to GND with low-ESR capacitor placed adjacent to bump. |
| B1 | GND | Ground reference - connects to PCB ground plane via low-inductance via; critical for RF stability and noise rejection. |
| B2 | RFIN | RF input - internally terminated to 50Ω and AC-coupled; accepts directional coupler output without external bias or matching. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated 50Ω RF Termination | Eliminates external 50Ω resistor and DC-blocking capacitor at RFIN, reducing BOM count and layout area in space-constrained handset designs. |
| Temperature-Stable Output Drift | Repeatable unit-to-unit thermal behavior enables factory calibration using nominal lookup tables instead of per-device characterization. |
| Ultra-Small UCSP™ Package | 1mm² footprint with 0.5mm pitch allows placement directly adjacent to PA output or coupler, minimizing parasitic trace inductance. |
| Wide Input Power Range | -25dBm to 0dBm detection range accommodates varying coupler coupling factors and PA back-off conditions without gain switching. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5511ACPZ-R7 | Wider frequency range (10MHz–6GHz), higher supply current (12mA), no integrated 50Ω termination. | Requires external 50Ω termination and DC-blocking; better suited for broadband test equipment than handset integration. | Select when multi-band coverage beyond 2GHz or higher accuracy at low input powers (<-30dBm) is required. |
| LT5537ESC6#TRMPBF | Narrower detection range (-40dBm to +15dBm), larger 6-lead SOT-23 package, ±1dB temp error over -40°C to +85°C. | Larger footprint and looser error spec limit use in compact, high-accuracy handset designs. | Prefer for cost-sensitive industrial RF monitors where size and ±0.5dB precision are not critical. |
Compared with ADL5511ACPZ-R7 and LT5537ESC6#TRMPBF, the MAX2209EBS+T10 delivers optimal trade-off of ultra-small size, integrated RF interface, and tight temperature-stable error - making it purpose-built for space- and accuracy-constrained WCDMA/HSDPA handset power control.

FAQ
What is the operating temperature range for the MAX2209EBS+T10?
The MAX2209EBS+T10 is specified to operate from -40°C to +85°C. Its detection error remains tightly controlled across this range - ±0.5dB at -5dBm input and ±1.5dB at -25dBm input - due to highly repeatable thermal drift characteristics that enable effective factory calibration using nominal lookup tables. This makes the MAX2209EBS+T10 suitable for consumer handheld environments with ambient temperature variation.
Does the MAX2209EBS+T10 require external RF matching components?
No, the MAX2209EBS+T10 integrates a 50Ω termination resistor and DC-blocking capacitor at the RFIN pin, eliminating the need for external matching networks when used with standard directional couplers. The B2 pin (RFIN) is internally biased and AC-coupled, allowing direct connection to coupler output without additional resistors or capacitors - reducing bill-of-materials and PCB area in compact handset designs.
What is the typical settling time of the MAX2209EBS+T10 after RF power changes?
The MAX2209EBS+T10 achieves full settling in less than 2µs when responding to RF power transitions at 836MHz, as verified in typical operating characteristics (Figure MAX2209 toc12). This fast response supports accurate power capture during rapid TPC (Transmit Power Control) command updates in HSDPA/HSUPA systems, ensuring reliable closed-loop PA control without latency-induced overshoot or undershoot.
Can the MAX2209EBS+T10 be used with 5V supply voltage?
Yes, the MAX2209EBS+T10 supports supply voltages from +2.7V to +5.0V. At VCC = 5.0V, supply current remains within 3.6mA to 6mA, and output voltage swing extends to ~1.0V - maintaining compatibility with 5V-tolerant ADC inputs. Its rail-to-rail output capability and stable performance across this range make the MAX2209EBS+T10 adaptable to both 2.8V baseband and 5V legacy system architectures.
Is the MAX2209EBS+T10 RoHS-compliant and lead-free?
Yes, the MAX2209EBS+T10 carries the "+" suffix, indicating a lead(Pb)-free and RoHS-compliant package per Maxim's packaging nomenclature. It uses a 4-bump UCSP™ wafer-level package with environmentally compliant finish and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL-1) requirements for standard reflow assembly.
