Product details
Overview
The MAX2207EBS+ from Maxim Integrated is a TDMA-optimized RF power detector in a 2×2 UCSP package, operating from 800MHz to 2GHz with 25dB dynamic range, ±1dB full-power temperature accuracy, and 2mA idle supply current. It interfaces directly with directional couplers via internal 50Ω termination and delivers monotonic voltage output for closed-loop PA control in dual-band TDMA handsets.
For engineers reviewing the MAX2207EBS+ datasheet, MAX2207EBS+ pinout, MAX2207EBS+ application, or MAX2207EBS+ equivalent, key selection criteria include its TDMA-specific low-current operation, 2µs turn-on time, 300ns response time at 800MHz, and compatibility with analog/digital power-control architectures requiring stable DC-coupled detection over industrial temperature range.
Technical Context
The MAX2207EBS+ implements a temperature-compensated peak-detection architecture with internal 50Ω RF input termination, enabling direct connection to directional couplers without external matching. Its shutdown logic input (RFIN/SHDN) supports dual-function pinning for RF signal injection and digital enable control.
It features externally adjustable averaging time constant via optional CFILTER capacitor, and delivers rail-to-rail compatible output voltage (0–2.5V) with 400µA source/sink capability-designed for direct interface to ADCs or op-amps in real-time transmit power monitoring systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 800MHz to 2GHz - supports full TDMA band coverage including 800/900/1800/1900MHz cellular bands |
| Dynamic Range | 25dB - enables accurate detection across typical TDMA PA output swing (−25dBm to 0dBm) |
| Temp Accuracy | ±1dB at full power - ensures <1% transmit power error over −40°C to +85°C without calibration |
| Idle Supply Current | 2mA - reduces system-level power consumption vs. MAX2206 (3.5mA) for battery-sensitive TDMA handsets |
| Response Time | 300ns at 800MHz - meets fast AGC loop timing requirements in burst-mode TDMA transmission |
| Turn-On Time | 2µs - allows rapid activation between TDMA time slots without detection lag |
| Input Impedance | 50Ω (internal termination) - eliminates need for external matching network when used with 50Ω coupler outputs |
Pinout & Package
MAX2207EBS+ uses a 2×2 mm, 0.5mm-pitch, 4-bump UCSP package with bottom-side solder bumps. The package footprint occupies only 1mm² PCB area and requires no leadframe or wirebonding.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | RFIN/SHDN | Dual-function terminal: accepts AC-coupled RF input from coupler AND serves as logic-controlled shutdown input (0V = off, ≥2.0V = on) |
| A2 | VCC | Single 2.7V–5.0V supply input; requires local 0.1µF bypass capacitor to GND for RF stability |
| B1 | GND | Ground reference for RF and analog sections; must connect to low-inductance ground plane using multiple vias |
| B2 | OUT | Analog DC output voltage proportional to RF input power; drives ADC inputs or op-amp buffers directly |
Key Features
| Feature | Design Value |
|---|---|
| TDMA-optimized current draw | 2mA idle supply current - extends battery life in TDMA handset PA control loops vs. 3.5mA alternatives |
| Integrated 50Ω termination | Eliminates external input resistor network - simplifies layout and improves impedance match stability across frequency |
| Temperature-compensated detection | ±1dB variation over −40°C to +85°C - removes need for system-level temperature compensation algorithms |
| Fast 300ns response at 800MHz | Enables real-time power tracking within TDMA burst envelope - supports tight transmit power tolerance specs |
| UCSP 2×2 mm footprint | 1mm² board area - fits within space-constrained front-end modules alongside PA and switch |

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+ | 40dB dynamic range, 3.5mA idle current, optimized for GSM/EDGE burst profiles | Higher current draw and wider range reduce suitability for TDMA battery life targets | Select MAX2206EBS+ only if GSM/EDGE coexistence or extended dynamic range is required |
| ADL5511ACPZ-R7 | 35dB range, 3.3V fixed supply, 5ns response, requires external 50Ω termination | Lacks integrated termination and TDMA-optimized current; better suited for wideband test equipment | Choose ADL5511ACPZ-R7 for high-speed instrumentation where sub-10ns response is critical |
Compared with MAX2206EBS+, the MAX2207EBS+ trades 15dB dynamic range for 43% lower idle current-directly improving TDMA handset talk time. Against ADL5511ACPZ-R7, it offers integrated termination and simpler biasing but slower response, making it preferable for cost-sensitive, space-constrained mobile front ends.

FAQ
What is the operating temperature range for the MAX2207EBS+?
The MAX2207EBS+ is specified for continuous operation from −40°C to +85°C. This industrial temperature range ensures reliable performance in handheld devices exposed to ambient extremes, and all electrical parameters-including ±1dB detection accuracy and 2mA idle current-are guaranteed across this full range without derating.
Does the MAX2207EBS+ require external passive components for basic operation?
Yes, the MAX2207EBS+ requires three external components for standard operation: a 0.1µF VCC bypass capacitor to GND, an AC-coupling capacitor on the RFIN/SHDN pin, and a pull-up or pull-down resistor for shutdown logic control. No external filter or op-amp is needed-the device provides fully compensated analog output ready for ADC sampling.
How does the MAX2207EBS+ differ from the MAX2205EBS+ in terms of RF input interface?
The MAX2207EBS+ uses an internal 50Ω RF input termination optimized for directional coupler interfaces, while the MAX2205EBS+ features high-impedance input (≈680Ω || jX) for resistive tapping from CDMA PAs. This makes MAX2207EBS+ incompatible with high-Z tap configurations but ideal for 50Ω-based TDMA front ends.
Can the MAX2207EBS+ be used in GSM/EDGE applications?
The MAX2207EBS+ can be used in GSM/EDGE applications, but it is not optimized for them. Its 25dB dynamic range and 2mA current are tailored for TDMA's narrower power envelope and battery constraints; GSM/EDGE typically benefits from the 40dB range and higher linearity of the MAX2206EBS+. Using MAX2207EBS+ in GSM may limit headroom at high power levels.
What is the function of the RFIN/SHDN pin on the MAX2207EBS+?
The RFIN/SHDN pin on the MAX2207EBS+ serves two simultaneous functions: it accepts the AC-coupled RF input signal from a directional coupler, and it accepts a logic-level shutdown control signal. Driving this pin below 0.6V disables the detector (reducing supply current to ≤10µA), while driving it above 2.0V enables normal operation-enabling single-pin power gating in space-constrained layouts.
