Product details
Overview
MAX2209EBS+T10G45 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. It features on-chip 50Ω termination and DC-blocking capacitor, requires only two external components, and targets WCDMA/HSDPA/HSUPA handset transmit power control.
For engineers reviewing the MAX2209EBS+T10G45 datasheet, MAX2209EBS+T10G45 pinout, MAX2209EBS+T10G45 application, or MAX2209EBS+T10G45 equivalent, key selection criteria include its -25dBm to 0dBm detection range, temperature-stable output behavior across -40°C to +85°C, 4-bump UCSP™ package footprint, and integration-ready RF input interface compatible with directional couplers.
Technical Context
The MAX2209EBS+T10G45 implements a bipolar process-based logarithmic detector architecture optimized for envelope tracking in cellular front-end modules. Its internal 50Ω RF termination enables direct connection to directional coupler outputs without external matching, while the DC-coupled output drives ADCs directly with sub-1µs settling time.
It operates from a single +2.7V to +5.0V supply, draws 3.6mA to 6mA quiescent current, and maintains <±0.5dB error at -5dBm input over full temperature range after room-temperature calibration-enabling lookup-table-based compensation in baseband processors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 800MHz to 2000MHz - supports dual-band WCDMA, HSDPA, and HSUPA uplink/downlink bands without re-tuning. |
| Detection Range | -25dBm to 0dBm - covers typical PA output power levels in mobile handset power amplifiers. |
| Residual Error (TA = -40°C to +85°C) | ±0.5dB at -5dBm input - enables accurate closed-loop transmit power control using factory-calibrated LUTs. |
| Supply Voltage | +2.7V to +5.0V - compatible with common baseband processor I/O rails and battery-sourced bias networks. |
| Supply Current | 3.6mA to 6mA - low quiescent draw minimizes impact on handset standby current budget. |
| Output Settling Time | <2µs - meets fast AGC loop timing requirements for burst-mode transmission in HSPA protocols. |
| Package | 4-bump, 1mm² UCSP™ (WLP) - 0.5mm pitch, 0.23mm height; enables ultra-compact RF front-end layout. |
Pinout & Package
The MAX2209EBS+T10G45 is housed in a 2×2, 0.5mm-pitch wafer-level package (UCSP™) with four solder bumps. The package measures 1.0mm × 1.0mm × 0.23mm and is RoHS-compliant (lead-free).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | DC output voltage proportional to RF input peak voltage; drives ADC input directly with minimal external filtering. |
| A2 | VCC | Positive supply input; must be bypassed to GND with capacitor placed adjacent to bump to suppress RF noise coupling. |
| B1 | GND | Ground reference; requires low-inductance connection to PCB ground plane via dedicated via near bump. |
| 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 |
|---|---|
| On-chip 50Ω termination | Eliminates need for external RF termination resistor, reducing BOM count and PCB area in space-constrained handset designs. |
| Integrated DC-blocking capacitor | Removes DC offset from RF path, enabling direct coupling from directional coupler without external series capacitor. |
| Temperature-stable output | Repeatability of ±0.5dB error across -40°C to +85°C allows use of single factory-generated LUT for all units. |
| Ultra-small UCSP™ package | 1mm² footprint and 0.23mm height support placement adjacent to PA modules in multi-layer RF front-end layouts. |
| Single-supply operation | Operates from +2.7V to +5.0V - compatible with standard baseband ASIC supply rails and eliminates need for dedicated bias regulators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power detector applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5511ACPZ-R7 | Wider frequency range (10MHz–6GHz), higher supply current (12mA), larger 8-lead LFCSP package. | Supports LTE and Wi-Fi bands beyond WCDMA; less suitable for ultra-compact handset layouts. | Choose ADL5511ACPZ-R7 when multi-band coverage including LTE Band 7/40 or 2.4GHz Wi-Fi is required. |
| LT5537ESC6#TRMPBF | Narrower detection range (-45dBm to -5dBm), lower supply voltage (2.7V to 3.6V), 6-lead SC-70 package. | Better suited for low-power IoT transmitters; insufficient dynamic range for WCDMA PA output monitoring. | Choose LT5537ESC6#TRMPBF only for sub-10dBm applications where ultra-low power consumption is critical. |
Compared with ADL5511ACPZ-R7 and LT5537ESC6#TRMPBF, the MAX2209EBS+T10G45 delivers optimal balance of compact size, WCDMA-optimized bandwidth, and calibrated accuracy for mobile handset power control-without requiring layout redesign or firmware changes for legacy 3G platforms.
