Product details
Overview
MAX2203EWT+T10 from Maxim Integrated is an RMS power detector IC for RF power monitoring in WCDMA, cdma2000®, and HSDPA/HSUPA transceivers. It operates from 800MHz to 2.0GHz, delivers 35mV/dB log slope (typ), supports -24dBm to +3dBm input range, and functions on a single 2.5V–4.2V supply across -40°C to +85°C. Its role is precision envelope-independent RF power measurement at baseband interface points.
For engineers reviewing the MAX2203EWT+T10 datasheet, MAX2203EWT+T10 pinout, MAX2203EWT+T10 application, or MAX2203EWT+T10 equivalent, key selection criteria include RMS accuracy under WCDMA modulation (0.1dB typ), temperature-induced detection error (±0.4dB), log conformance over 10dB steps, enable-controlled shutdown current (≤10µA), and 6-bump WLP package compatibility with high-density RF front-end layouts.
Technical Context
The MAX2203EWT+T10 implements true RMS detection using BiCMOS process technology, enabling consistent output voltage regardless of input signal crest factor - critical for CDMA/WCDMA waveforms with high peak-to-average ratios (e.g., 6.5dB for DPCCH + 5DPDCH). Its internal architecture integrates RF input conditioning, RMS-to-DC conversion, and buffered analog output without external calibration.
It features integrated enable logic (RFIN/ENA dual-function pin), FILT node for external RC filtering, and GND pins optimized for low-inductance PCB grounding. The device requires no external termination when used with directional couplers in dual-band configurations, as confirmed by Figure 1's system-level connection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 800MHz to 2000MHz - covers cellular bands including PCS (1850–1990MHz) and cellular (824–960MHz) for multi-standard support. |
| Detection Range | -24dBm to +3dBm - enables accurate closed-loop transmit power control across full dynamic range of WCDMA/cdma2000 PA stages. |
| Log Slope | 35mV/dB (typ) - provides predictable, linear-in-dB output scaling for direct ADC interfacing without digital compensation. |
| RMS Accuracy | 0.1dB (typ) with WCDMA modulation - ensures minimal error in power control loops under real-world modulated signals. |
| Temp Error | ±0.4dB over -40°C to +85°C - maintains stable calibration across extended industrial temperature operation without recalibration. |
| Supply Voltage | 2.5V to 4.2V - compatible with Li-ion battery rails and regulated 2.8V/3.3V supplies in portable RF systems. |
| Shutdown Current | ≤10µA - enables low-power idle states during TDD burst gaps or sleep modes in mobile handsets. |
Pinout & Package
The MAX2203EWT+T10 is housed in a 6-bump wafer-level package (WLP), measuring 1.5mm × 1.1mm × 0.6mm, with bottom-side solder bumps for compact RF layout integration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | RFIN/ENA | Combined RF input and enable logic terminal; driven high (>1.1V) for active mode, low (<0.6V) for shutdown; internal 50kΩ pull-down. |
| A2, B1 | GND | Dedicated ground terminals requiring low-inductance vias to PCB ground plane for RMS accuracy and noise immunity. |
| B2 | FILT | Internal filter node; must be bypassed with ≥220pF capacitor (X5R/X7R) adjacent to package for output ripple suppression. |
| C1 | VCC | Power supply input; requires local 0.1µF X5R/X7R ceramic bypass capacitor placed within 1mm of bump. |
| C2 | OUT | Analog DC output voltage proportional to input RF power; connects directly to ADC input or low-pass RC network. |
Key Features
| Feature | Design Value |
|---|---|
| True RMS detection | Delivers stable output independent of signal crest factor - essential for accurate power control with WCDMA/cdma2000 modulated waveforms. |
| Integrated enable function | Single-pin RFIN/ENA simplifies control logic and reduces PCB routing complexity in TDD systems requiring rapid on/off cycling. |
| Low temperature drift | ±0.4dB detection error over full -40°C to +85°C range eliminates need for temperature-compensated lookup tables in firmware. |
| Minimal external components | Requires only three passive components (two capacitors, one resistor) for full operation - reduces bill-of-materials and board area. |
| WLP footprint | 1.5mm × 1.1mm package enables placement directly adjacent to power amplifiers and couplers in space-constrained mobile RF modules. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RMS power detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADL5511ACPZ-R7 | Wider frequency range (up to 4.5GHz), higher supply current (12mA), larger 16-lead LFCSP package. | Targeted at microwave test equipment and LTE-A carrier aggregation, not optimized for mobile handset size/power constraints. | Select ADL5511ACPZ-R7 only if >2GHz coverage or higher accuracy at millimeter-wave frequencies is required. |
| LT5537IMS8#TRPBF | Narrower detection range (-35dBm to -5dBm), lower log slope (25mV/dB), operates down to 10MHz - includes internal temperature compensation. | Suited for low-power IoT transceivers and sub-GHz ISM band applications, not validated for WCDMA/cdma2000 PAR profiles. | Choose LT5537IMS8#TRPBF for battery-powered narrowband systems where ultra-low detection threshold matters more than cellular bandwidth. |
Compared with ADL5511ACPZ-R7 and LT5537IMS8#TRPBF, the MAX2203EWT+T10 uniquely balances cellular-band RMS accuracy, ultra-small WLP footprint, and low-quiescent-current shutdown - making it the optimal choice for space- and power-constrained 3G mobile RF front ends.

FAQ
What is the RF input frequency range supported by the MAX2203EWT+T10?
The MAX2203EWT+T10 supports an RF input frequency range from 800MHz to 2000MHz. This covers all major 3G cellular bands including cellular (824–960MHz), PCS (1850–1990MHz), and IMT-2000 (1920–2170MHz), as verified in the Absolute Maximum Ratings and AC Electrical Characteristics sections of the official datasheet.
Does the MAX2203EWT+T10 require external calibration for WCDMA signals?
No, the MAX2203EWT+T10 does not require external calibration for WCDMA signals. Its RMS accuracy is specified at 0.1dB (typ) under WCDMA modulation (DPCCH + 1DPDCH), and log conformance error remains within ±1.3dB over 10dB input steps - both guaranteed across temperature and frequency per datasheet testing.
How is the enable function implemented on the MAX2203EWT+T10?
The MAX2203EWT+T10 implements enable via the RFIN/ENA pin (bump A1): driving this pin above 1.1V activates the detector, while pulling it below 0.6V places the device in shutdown mode drawing ≤10µA. An internal 50kΩ pull-down resistor ensures safe default state, and external series resistance >1kΩ prevents RF loading.
What package type and dimensions does the MAX2203EWT+T10 use?
The MAX2203EWT+T10 uses a 6-bump wafer-level package (WLP) with top mark "AA", measuring 1.5mm × 1.1mm × 0.6mm. Its land pattern follows Maxim's W61B1+1 package code (Document No. 21-0217), and it is lead(Pb)-free/RoHS-compliant per the +T10 ordering suffix.
Can the MAX2203EWT+T10 be used with directional couplers without external termination?
Yes, the MAX2203EWT+T10 can be used with directional couplers without external termination when configured per Figure 1 in the datasheet - specifically in dual-coupler arrangements where termination resistors are omitted. This is enabled by its internal biasing and input impedance characteristics, reducing component count in RF front-end designs.
