Product details
Overview
The MAX2207EBS-T from Maxim Integrated is a TDMA-optimized RF power detector operating from 800MHz to 2GHz, delivering monotonic voltage output proportional to input RF power with ±1dB full-power accuracy and ±2.5dB low-power accuracy over –40°C to +85°C. It features internal 50Ω termination, 25dB dynamic range, and reduced current consumption for battery-sensitive TDMA handset PA control loops.
For engineers reviewing the MAX2207EBS-T datasheet, MAX2207EBS-T pinout, MAX2207EBS-T application, or MAX2207EBS-T equivalent, key selection criteria include its 2×2 UCSP package footprint, shutdown logic interface on RFIN/SHDN, temperature-compensated peak detection architecture, and compatibility with directional coupler-based RF power monitoring in dual-band TDMA handsets and PA modules.
Technical Context
The MAX2207EBS-T implements a temperature-compensated peak-detection architecture with integrated 50Ω RF input termination, enabling direct connection to directional couplers without external matching. Its output voltage scales linearly with log input power across 25dB range, with response time under 300ns at high input levels and <15µs at low levels.
Shutdown is controlled via the RFIN/SHDN pin: driven low to reduce supply current to ≤10µA, high or tied to VCC to enable operation. The device requires only three external components-no op amp or filter-and interfaces directly to ADCs in discrete-time power control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 800MHz to 2GHz - supports full TDMA band operation including 800/900/1800/1900MHz cellular bands |
| Dynamic Range | 25dB - enables accurate power measurement across typical TDMA PA output swing (–10dBm to +15dBm) |
| Temp Accuracy | ±1dB at full power, ±2.5dB at lowest power - ensures stable closed-loop PA control across industrial temperature range |
| Supply Current | 2mA to 3.5mA idle - optimized for low-power TDMA handset operation vs. 3.5–5.5mA in MAX2206 |
| Input Impedance | 50Ω (internal) - eliminates need for external matching network when used with 50Ω directional couplers |
| Shutdown Current | ≤10µA - reduces system standby power in TDMA burst-mode transmission schemes |
| Package | 2×2 mm UCSP, 0.5mm pitch, 4-pin - occupies only 1mm² PCB area, compatible with space-constrained handset modules |
Pinout & Package
MAX2207EBS-T uses a 4-bump 2×2 mm UCSP package with 0.5mm pitch and bottom-solder interconnect. Pin layout is standardized across MAX2205–MAX2208 family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | RFIN/SHDN | Combined RF input and digital shutdown control - AC-coupled RF path; logic-low disables detector and cuts supply current |
| A2 | VCC | Power supply (2.7V to 5.0V) - requires local bypass capacitor to GND for RF stability and noise rejection |
| B1 | GND | Ground reference - must connect to low-inductance ground plane using multiple vias for RF integrity |
| B2 | OUT | Analog detector output - provides temperature-compensated DC voltage proportional to RF input power for ADC sampling |
Key Features
| Feature | Design Value |
|---|---|
| Internal 50Ω termination | Enables direct coupling to directional couplers without external resistors or matching networks |
| Temperature compensation | Maintains ±1dB detection accuracy over –40°C to +85°C, critical for outdoor TDMA base station and mobile handset reliability |
| No external op amp required | Reduces BOM count and PCB area in compact PA feedback paths, simplifying layout and calibration |
| 25dB dynamic range | Accurately tracks TDMA PA output across full transmit power envelope, supporting precise closed-loop control |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF power detection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2206EBS-T | 40dB dynamic range, 3.5–5.5mA supply current, same 2×2 UCSP package and pinout | Optimized for GSM/EDGE with wider dynamic range; higher current draw unsuitable for TDMA battery life targets | Select MAX2206EBS-T only when >35dB measurement range is required and current budget permits |
| MAX2208EBS-T | Same 25dB range and current as MAX2207EBS-T but includes integrated filter for CDMA average power detection | Designed for CDMA pilot+DCCH signal averaging; lacks TDMA-specific optimization in response time and biasing | Prefer MAX2207EBS-T for pure TDMA systems; choose MAX2208EBS-T only if CDMA coexistence or multi-standard support is needed |
Compared with MAX2206EBS-T, MAX2207EBS-T trades 15dB dynamic range for 1.5mA lower quiescent current-critical for TDMA handset battery life-while retaining identical pinout, package, and temperature accuracy. Against MAX2208EBS-T, it removes the CDMA-optimized filter to improve TDMA burst response speed and simplify analog front-end design.

FAQ
What is the operating temperature range of the MAX2207EBS-T?
The MAX2207EBS-T is rated for continuous operation from –40°C to +85°C. This industrial temperature range is confirmed in the Absolute Maximum Ratings table and supported by temperature-compensated performance data across the full span, ensuring reliable RF power detection in outdoor TDMA handsets and base station equipment.
Does the MAX2207EBS-T require external filtering for TDMA applications?
No, the MAX2207EBS-T does not require external filtering for standard TDMA applications. It delivers accurate peak-detection output directly to an ADC without additional passive components, as verified in the Typical Operating Characteristics and Applications Information sections of the datasheet. The device's internal architecture eliminates the need for external op amps or RC filters.
What is the RF input impedance of the MAX2207EBS-T?
The MAX2207EBS-T features an internal 50Ω RF input termination, explicitly stated in the General Description and Pin Description sections. This allows direct connection to 50Ω directional couplers without external matching networks, simplifying layout and improving measurement consistency across frequency and temperature.
How does the shutdown function work on the MAX2207EBS-T?
The MAX2207EBS-T uses the RFIN/SHDN pin for combined RF input and shutdown control. Driving this pin low (≤0.6V) places the device in shutdown mode, reducing supply current to ≤10µA. Driving it high (≥2.0V) or connecting it to VCC enables normal operation. This dual-function pin saves board space and simplifies control logic in TDMA burst-mode systems.
Is the MAX2207EBS-T pin-compatible with other devices in the MAX2205–MAX2208 family?
Yes, the MAX2207EBS-T shares identical 2×2 UCSP package dimensions, 0.5mm pitch, and 4-pin layout with MAX2205EBS-T, MAX2206EBS-T, and MAX2208EBS-T. Pin assignments (RFIN/SHDN, VCC, GND, OUT) are fully consistent across the family, enabling drop-in substitution in existing layouts when functional requirements align.
