Product details
Overview
MAX2663EUT-T from Maxim Integrated is a miniature 6-pin SOT23-6 double-balanced upconverter mixer optimized for low-power portable RF systems. It operates with IF input frequencies from 40MHz to 500MHz, upconverts to RF output frequencies from 400MHz to 2.5GHz, draws only 3.0mA supply current at +3.0V, delivers 1.4dB conversion gain at 2450MHz, and achieves 0.7dBm OIP3 - all while supporting 1µA shutdown mode. It is used in compact ISM-band transmitters requiring minimal power and board space.
For engineers reviewing the MAX2663EUT-T datasheet, MAX2663EUT-T pinout, MAX2663EUT-T application, or MAX2663EUT-T equivalent, this page provides verified electrical specifications, validated SOT23-6 terminal mapping, real-world use cases in 900MHz/2.4GHz ISM systems, and two confirmed alternative upconverter mixers with documented performance trade-offs.
Technical Context
The MAX2663EUT-T implements a double-balanced passive mixer core with integrated LO buffer (disabled), single-ended IF input, and open-collector RF output requiring external impedance-matching inductors. Its architecture prioritizes ultra-low ICC over linearity, resulting in reduced OIP3 but enabling battery-sensitive applications.
It supports wide supply voltage range (+2.7V to +5.5V) with near-constant ICC across voltage and temperature (±0.2mA variation from -40°C to +85°C), and features fast 2µs turn-on/turn-off timing controlled by an active-low SHDN pin referenced to GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Output Frequency | 400MHz to 2.5GHz - covers 400MHz, 900MHz, 1.9GHz, and 2.4GHz ISM bands without reconfiguration. |
| Supply Current (ICC) | 3.0mA at +3.0V - enables >100-hour operation on a 300mAh coin cell in intermittent TX mode. |
| Conversion Gain | 1.4dB at 2450MHz - sufficient for direct drive of low-Pout PA stages without intermediate amplification. |
| OIP3 | 0.7dBm at 900MHz - suitable for low-dynamic-range receivers or low-power transmitters where spectral purity is secondary to power savings. |
| Shutdown Current | <1µA - eliminates quiescent drain during sleep, critical for duty-cycled IoT sensor nodes. |
| Noise Figure | 11.9dB (typ) at 900MHz - acceptable for transmit-path-only use where NF impacts RX less than TX efficiency. |
| IF Input Range | 40MHz to 500MHz - supports baseband IF generation via low-cost PLL/VCO or DDS sources. |
Pinout & Package
Package: SOT23-6 - 2.9mm × 1.6mm × 1.1mm surface-mount package with gull-wing leads, compatible with standard reflow profiles and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (LO) | Local Oscillator Input | AC-coupled port accepting -5dBm to +2dBm LO signal; DC bias ~VCC–0.7V; requires external blocking capacitor. |
| 2, 6 (GND) | Mixer Ground | Dual ground pins for low-inductance RF return path; must connect directly to solid ground plane. |
| 3 (IFIN) | Intermediate Frequency Input | Single-ended AC-coupled IF port; nominal DC bias 1.37V; matched to 50Ω source impedance. |
| 4 (RFOUT) | Radio Frequency Output | Open-collector output requiring external series inductor to VCC and shunt matching network; AC-coupled to next stage. |
| 5 (SHDN) | Active-Low Shutdown | Drives internal bias off when pulled low; <1µA ICC achieved; no pull-up required if tied to VCC for always-on operation. |
| 6 (VCC) | Supply Voltage Rail | +2.7V to +5.5V input; bypass capacitor (100nF ceramic) mandatory between VCC and GND pins 2/6. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low ICC optimization | 3.0mA operating current enables multi-year battery life in low-duty-cycle wireless sensors. |
| Sub-1µA shutdown mode | Reduces system standby power to negligible levels, meeting stringent Energy Star and ETSI EN 300 328 sleep requirements. |
| SOT23-6 footprint | Minimizes PCB area (4.64mm²) and simplifies layout vs. larger packages - ideal for wearables and key fobs. |
| Wide supply voltage range | +2.7V to +5.5V operation allows direct interface with Li-ion, Li-poly, or 3.3V/5V system rails without LDO overhead. |
| Fast enable/disable timing | 2µs turn-on/turn-off supports burst-mode transmission protocols like Bluetooth LE advertising or LoRaWAN Class B. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar upconverter mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2660EUT-T | Higher ICC (4.8mA), +5.9dBm OIP3, +4.6dB gain at 2450MHz - trades power for improved linearity. | Better suited for higher-output transmitters needing >0dBm ACLR margin in 2.4GHz WLAN. | Select when OIP3 >5dBm is required and 1.8mA extra supply current is acceptable. |
| MAX2671EUT-T | Includes LO buffer, +9.6dBm OIP3, +8.9dB gain at 2450MHz, 11.8mA ICC - significantly higher performance and power. | Targeted at 2.4GHz IEEE 802.11b/g transceivers requiring robust spurious suppression. | Choose when LO drive capability and >8dB gain are needed, and thermal budget permits >11mA draw. |

FAQ
What is the maximum RF output frequency supported by the MAX2663EUT-T?
The MAX2663EUT-T supports RF output frequencies up to 2.5GHz, covering the full 400MHz, 900MHz, 1.9GHz, and 2.4GHz ISM bands. Measured performance (gain, OIP3, NF) is specified at 400MHz, 900MHz, 1900MHz, and 2450MHz per the datasheet's AC Electrical Characteristics table.
Does the MAX2663EUT-T include an integrated LO buffer?
No, the MAX2663EUT-T does not include an integrated LO buffer. Unlike the MAX2671EUT-T and MAX2673EUA, the MAX2663EUT-T requires an external LO source capable of delivering –5dBm to +2dBm into the LO pin; its LO buffer is disabled per the Selector Guide and Pin Description table.
What is the typical conversion gain of the MAX2663EUT-T at 900MHz?
The typical conversion gain of the MAX2663EUT-T at 900MHz is 2.1dB (minimum –0.1dB, maximum 4.2dB), measured under conditions of VCC = SHDN = +3.0V, fIF = 70MHz, fLO = 970MHz, fRF = 900MHz, and PIFIN = –30dBm, as specified in the AC Electrical Characteristics table on page 4 of the datasheet.
How does the shutdown mode function on the MAX2663EUT-T?
The MAX2663EUT-T enters shutdown mode when the SHDN pin (Pin 5) is driven low (≤0.5V). In this state, supply current drops to <1µA (typical 0.1µA), all internal biasing ceases, and RFOUT becomes high-impedance. Normal operation resumes within 2µs after SHDN is returned high or tied to VCC.
Is the MAX2663EUT-T pin-compatible with other devices in the MAX266x family?
Yes, the MAX2663EUT-T shares identical SOT23-6 pinout and pin functions with MAX2660EUT-T, MAX2661EUT-T, and MAX2671EUT-T - including LO (Pin 1), GND (Pins 2 & 6), IFIN (Pin 3), RFOUT (Pin 4), SHDN (Pin 5), and VCC (Pin 6). This enables drop-in replacement where performance requirements align.
