Product details
Overview
MAX2209EBS+TG45 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. It is used in WCDMA handset transmit power control loops following directional couplers.
For engineers reviewing the MAX2209EBS+TG45 datasheet, MAX2209EBS+TG45 pinout, MAX2209EBS+TG45 application, or MAX2209EBS+TG45 equivalent, key selection criteria include temperature-stable detection error across -40°C to +85°C, integrated 50Ω RF termination, ultra-small 4-bump UCSP™ package, and compatibility with baseband ADC interfaces in HSDPA/HSUPA transceivers.
Technical Context
The MAX2209EBS+TG45 implements a bipolar process-based logarithmic detector architecture optimized for envelope tracking in cellular front-end modules. Its output voltage (e.g., 0.88V at -5dBm, 836MHz) scales linearly with input RF voltage-not power-enabling precise peak-voltage-based closed-loop PA control.
It features on-chip 50Ω RF termination and DC-blocking capacitor, eliminating external matching components at RFIN. The output drives ADC inputs directly, with source/sink current capability up to 1800μA/525μA, supporting low-impedance signal chain integration without buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 800MHz to 2000MHz - supports dual-band WCDMA, HSDPA, and HSUPA bands without re-tuning. |
| Detection Range | -25dBm to 0dBm - covers full transmit power range of mobile handset PAs including back-off regions. |
| Residual Error | ±0.5dB at -5dBm, ±1.5dB at -25dBm (TA = -40°C to +85°C) - enables single-point room-temp calibration with minimal firmware compensation. |
| Supply Voltage | +2.7V to +5.0V - compatible with standard baseband supply rails and eliminates need for dedicated LDO. |
| Output Current Drive | 750–1800μA source / 300–525μA sink - sufficient to drive 10kΩ ADC input impedance with <1mV droop. |
| Package | 4-bump UCSP™ (2mm × 2mm, 0.5mm pitch) - reduces PCB area by >70% vs. SOT-23, critical for compact handset layouts. |
| Thermal Resistance | 335°C/W (θJA) - supports continuous operation at 6mA supply current within thermal limits up to +85°C ambient. |
Pinout & Package
MAX2209EBS+TG45 is housed in a lead(Pb)-free, RoHS-compliant 4-bump wafer-level package (UCSP™), measuring 2mm × 2mm with 0.5mm bump pitch. The top mark is "AGJ".
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | OUT | Detector analog output - delivers calibrated DC voltage proportional to RF peak voltage; connects directly to baseband ADC input. |
| A2 | VCC | Positive supply input - requires local 100nF ceramic bypass capacitor to GND for RF stability and noise rejection. |
| B1 | GND | Analog ground reference - must connect via low-inductance path (e.g., multiple vias) to solid PCB ground plane. |
| B2 | RFIN | RF input port - internally terminated to 50Ω and AC-coupled; accepts directional coupler output without external matching. |
Key Features
| Feature | Design Value |
|---|---|
| Temperature-Stable Detection | ±0.5dB max error over -40°C to +85°C after single-point room-temp calibration - reduces factory calibration time and firmware complexity. |
| Integrated RF Interface | On-chip 50Ω termination and DC-blocking capacitor - eliminates two external components and layout sensitivity near RFIN. |
| Ultra-Small Footprint | 1mm² die area in 2mm × 2mm UCSP™ - enables placement adjacent to PA modules in space-constrained RF front-end designs. |
| Single-Supply Operation | 2.7V to 5.0V supply range - interoperates with existing 3.3V or 5V baseband power domains without level-shifting. |
| Fast Settling Time | ≤2μs settling from RF ON/OFF (836MHz, -5dBm) - supports dynamic TDD burst-mode power control in HSDPA/HSUPA. |

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), larger 3mm × 3mm LFCSP package. | Supports LTE and 5G NR bands beyond 2GHz; less suitable for ultra-compact WCDMA handset layouts. | Select when multi-standard (LTE/WCDMA) coverage and higher-frequency operation are required; accept larger board area and higher quiescent power. |
| LT5537EMS#TRPBF | Narrower detection range (-35dBm to -5dBm), lower supply current (2.5mA), 3mm × 3mm MSOP package. | Better suited for low-power IoT transmitters; lacks integrated 50Ω termination and requires external matching. | Select for battery-powered devices needing extended dynamic range at low input powers; add external 50Ω resistor and AC coupling if replacing MAX2209EBS+TG45. |

FAQ
What is the operating temperature range for MAX2209EBS+TG45?
The MAX2209EBS+TG45 operates over an industrial temperature range of -40°C to +85°C. Its detection error remains tightly controlled across this range-±0.5dB at -5dBm input after room-temperature calibration-making it suitable for handheld devices exposed to ambient thermal cycling without recalibration.
Does MAX2209EBS+TG45 require external components for RF input interfacing?
No, the MAX2209EBS+TG45 integrates a 50Ω termination resistor and DC-blocking capacitor on-chip at the RFIN pin (B2). This eliminates the need for external matching networks or coupling capacitors, simplifying layout and improving repeatability in high-volume WCDMA handset manufacturing.
What is the typical settling time of MAX2209EBS+TG45 after RF power transitions?
The MAX2209EBS+TG45 achieves full output settling in ≤2μs following RF ON/OFF transitions at 836MHz and -5dBm input. This fast response supports time-division duplex (TDD) protocols like HSDPA and HSUPA, where rapid power ramping between slots is essential for spectral efficiency and regulatory compliance.
Can MAX2209EBS+TG45 be used with 5V supply voltage?
Yes, the MAX2209EBS+TG45 supports supply voltages from +2.7V to +5.0V. At VCC = 5.0V, its output voltage swing increases proportionally while maintaining specified linearity and error performance, enabling direct use in 5V baseband subsystems without level-shifting circuitry.
Is MAX2209EBS+TG45 RoHS-compliant and lead(Pb)-free?
Yes, MAX2209EBS+TG45 carries the "+" suffix indicating full RoHS compliance and lead(Pb)-free construction. Its UCSP™ package uses matte tin bump plating and meets JEDEC J-STD-020 moisture sensitivity level 1 (MSL1), supporting standard reflow soldering profiles.
