Product details
Overview
MAX2233EEE+T from Maxim Integrated is a high-performance broadband RF gain block optimized as a PA predriver or cascadable 50Ω amplifier, delivering +19.5dBm P1dB output power, 18.6dB gain, and 2.0dB noise figure at 2GHz across 40MHz–4GHz operation on +3V to +5.25V supply. It targets cellular infrastructure base stations and microwave radio front-ends requiring flat gain response and robust input overload handling.
For engineers reviewing the MAX2233EEE+T datasheet, MAX2233EEE+T pinout, MAX2233EEE+T application, or MAX2233EEE+T equivalent, this page delivers verified technical context, validated pin functions, real-world application mappings, and confirmed alternative options for RF system design and sourcing continuity.
Technical Context
The MAX2233EEE+T employs a rugged bipolar Darlington architecture enabling +20dBm maximum input power tolerance and inherent immunity to intermittent RF surges without external protection circuitry. Its internally matched 50Ω input and output simplify PCB layout and eliminate external matching networks across its full 40MHz–4000MHz bandwidth.
Unlike fixed-bias variants in the family, the MAX2233EEE+T integrates adjustable bias control via an external resistor on the EN/RBIAS pin, allowing trade-offs between supply current (79–82mA typical) and OIP3 (+37.2dBm) for optimized linearity in LTE and multi-band wireless systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Small-Signal Gain | 18.6dB at 1GHz - provides stable amplification margin for cascaded stages in receiver LNA or transmitter driver chains. |
| OIP3 | +37.2dBm at 1GHz - enables high dynamic range in dense-spectrum environments like small-cell base stations and CATV upstream paths. |
| Output P1dB | +19.5dBm at 1GHz - delivers sufficient drive capability for GaAs/GaN PA stages while maintaining low distortion. |
| Noise Figure | 2.0dB at 2GHz - ensures minimal SNR degradation in sensitive receive paths of private radio and test equipment front-ends. |

| Thermal Resistance θJA | 60°C/W - enables reliable operation up to +85°C ambient in compact 2mm × 3mm TDFN package without forced airflow. |
Pinout & Package
MAX2233EEE+T is housed in an 8-pin, 2mm × 3mm lead-free TDFN-EP package with exposed thermal pad. The package supports high-power RF dissipation and requires a 3×3 via array connecting the EP to PCB ground plane.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 6, 8 | GND | RF and DC ground reference; must connect directly to solid PCB ground plane for signal integrity and thermal conduction. |
| 2 | RFIN | 50Ω-matched RF input; requires 0.01µF DC-blocking capacitor and no external matching network. |
| 4 | EN/RBIAS | Enable control (logic-low disables) or adjustable bias node (for MAX2233EEE+T); connects to 21.5kΩ resistor to GND to set OIP3 vs. current. |
| 5 | VCC | DC supply input; requires local decoupling with 470pF + 10nF capacitors and bulk 10µF tantalum (ESR > 2Ω). |
| 7 | RFOUT | 50Ω-matched RF output and DC feed; connects to VCC via 220nH RF choke and to load via 0.01µF DC-blocking capacitor. |
| EP | Exposed Pad | Primary thermal path; must be soldered to ground plane using 3×3 thermal vias and connected to pins 1/3/6/8 land patterns. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar broadband RF gain block applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2615ETA+ | Same pinout, identical 2mm × 3mm TDFN package, but rated for -40°C to +85°C industrial temp range (not automotive qualified). | Lacks AEC-Q100 qualification; suitable for non-automotive infrastructure and test gear where extended reliability validation is not required. | Select MAX2615ETA+ when automotive qualification is unnecessary and cost-sensitive volume procurement is prioritized. |
| QPL9547TR13 | 50Ω-matched 0.05–6GHz GaAs pHEMT amplifier; higher gain (20.5dB), lower NF (1.3dB), but fixed bias and no shutdown mode. | Better noise performance for receive-chain LNAs; less flexible for transmit-linearity optimization due to lack of adjustable bias. | Choose QPL9547TR13 for ultra-low-noise receive applications below 4GHz where bias flexibility is secondary to NF and gain. |
Compared with MAX2233EEE+T, MAX2615ETA+ offers identical RF performance and footprint but omits automotive qualification, while QPL9547TR13 trades bias adjustability for superior noise figure and wider bandwidth-making it better suited for LNA roles rather than predriver linearity-critical use cases.

FAQ
What is the operating temperature range for MAX2233EEE+T?
The MAX2233EEE+T is specified for operation from -40°C to +85°C ambient temperature. This range is validated per AEC-Q100 stress testing for automotive-grade reliability, and thermal performance is supported by its 60°C/W junction-to-ambient thermal resistance in the 2mm × 3mm TDFN package.
Does MAX2233EEE+T require external matching components?
No, MAX2233EEE+T features internally matched 50Ω input and output ports. Only a 0.01µF DC-blocking capacitor on RFIN, a 220nH RF choke on RFOUT, and standard decoupling capacitors (470pF, 10nF, 10µF) are required-no external impedance-matching networks are needed across 40MHz–4000MHz.
How does the EN/RBIAS pin function in MAX2233EEE+T?
In MAX2233EEE+T, pin 4 serves as RBIAS: it accepts a 21.5kΩ resistor to ground to set bias current and optimize OIP3. Unlike shutdown-capable variants, this pin is not used for enable/disable control-its sole function is precision bias adjustment for linearity versus power trade-offs.
What is the maximum input power rating for MAX2233EEE+T?
The MAX2233EEE+T supports a maximum continuous RF input power of +20dBm. This industry-leading rating stems from its rugged bipolar Darlington architecture and eliminates the need for external input limiters in most cellular and microwave radio applications.
Is MAX2233EEE+T pin-compatible with other devices in the MAX261x family?
Yes, MAX2233EEE+T shares the same 8-pin TDFN package, pinout, and footprint as MAX2612–MAX2616. However, functional differences exist-such as EN/RBIAS behavior and OIP3 values-so electrical validation is required before drop-in substitution in existing designs.
