Product details
Overview
MAX2044ETP+T from Maxim Integrated is a SiGe high-linearity upconversion/downconversion mixer for 2300MHz–4000MHz RF bands, delivering +32.5dBm input IP3, 8.5dB noise figure, and 7.7dB conversion loss at 5V supply with 138mA current draw. It integrates an LO buffer and on-chip baluns for single-ended RF/LO inputs and supports low-side or high-side LO injection in LTE, WiMAX, and MMDS base station transceivers.
For engineers reviewing the MAX2044ETP+T datasheet, MAX2044ETP+T pinout, MAX2044ETP+T application, or MAX2044ETP+T equivalent, this page provides verified RF mixer specifications including LO drive range (–3 to +3dBm), IF bandwidth (50–500MHz), thermal performance (–40°C to +85°C), and package-validated layout compatibility with MAX2039/MAX2041/MAX2042 families.
Technical Context
The MAX2044ETP+T implements a double-balanced passive mixer core with integrated SiGe LO buffer and monolithic RF/LO baluns-enabling true single-ended operation without external transformers. Its ultra-wide 2600–4300MHz LO range supports both low-side and high-side injection across 2.5GHz and 3.5GHz infrastructure bands.
Performance is stabilized across temperature via low conversion loss drift (0.008–0.01 dB/°C) and tight IIP3 variation (±0.2 dB over –40°C to +85°C), while spurious rejection (e.g., 68dBc 2RF–2LO at PRF = –10dBm) meets stringent wireless infrastructure spectral purity requirements.
Key Specifications

Pinout & Package
The MAX2044ETP+T is housed in a 20-pin thin QFN (5mm × 5mm) with exposed thermal pad (EP), optimized for RF grounding and thermal dissipation in high-density wireless PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Single 3.3V or 5.0V rail powers entire mixer core, LO buffer, and bias circuitry. |
| GND | Ground reference | All 5 ground pins (GND1–GND5) must be connected to low-inductance RF ground plane via multiple vias. |
| RF+ | Differential RF input (non-inverting) | Accepts single-ended RF via internal balun; requires 50Ω match to minimize return loss (16–23dB). |
| RF– | Differential RF input (inverting) | Completes differential RF path; internal balun eliminates need for external RF transformer. |
| LO+ | Differential LO input (non-inverting) | Accepts single-ended LO via internal balun; supports –3 to +3dBm drive with 14–19dB return loss. |
| LO– | Differential LO input (inverting) | Completes differential LO path; integrated buffer ensures consistent LO drive across temperature. |
| IF+ | Differential IF output (non-inverting) | 50Ω nominal differential output; requires external 1:1 transformer for single-ended IF interface. |
| IF– | Differential IF output (inverting) | Paired with IF+; differential output improves common-mode noise rejection in IF chain. |
| LOBIAS | LO buffer bias control | External resistor sets LO buffer current; enables reduced-power mode (lower IIP3, higher NF trade-off). |
| EP | Exposed thermal pad | Must be soldered to solid copper thermal plane; critical for maintaining TJ ≤ +150°C at 5W dissipation. |

FAQ
What is the recommended LO drive level for MAX2044ETP+T?
The MAX2044ETP+T specifies a nominal LO drive of 0dBm, with guaranteed operation across –3dBm to +3dBm. Operating within this range ensures optimal conversion loss (7.7dB), IIP3 (+32.5dBm), and spurious performance (68dBc 2RF–2LO). Drive levels outside this range degrade linearity and increase conversion loss, so external LO amplification should be calibrated to stay within spec.
Does MAX2044ETP+T support both upconversion and downconversion modes?
Yes, the MAX2044ETP+T is a bidirectional mixer fully characterized for both upconversion and downconversion. In downconverter mode (e.g., 3500MHz RF → 300MHz IF), it achieves 7.7dB conversion loss and 8.5dB noise figure. In upconverter mode (e.g., 200MHz IF → 3500MHz RF), it maintains 7.7dB loss and +33.5dBm IIP3 at 5V-enabling reuse in TDD/FDD transceivers without hardware changes.
What is the thermal resistance and maximum junction temperature for MAX2044ETP+T?
The MAX2044ETP+T has a junction-to-case thermal resistance (BJC) of +13°C/W and a maximum junction temperature of +150°C. With its exposed pad (EP) properly soldered to a thermal plane, the device sustains continuous 5W power dissipation. At 138mA and 5V, typical power draw is 690mW-well within thermal limits when ambient case temperature stays ≤ +85°C per datasheet specification.
Can MAX2044ETP+T operate from a 3.3V supply?
Yes, the MAX2044ETP+T is fully specified for 3.3V operation, drawing 121mA typical supply current. At 3.3V, it delivers 7.7dB conversion loss, +29.5dBm IIP3, and 8.5dB noise figure-slightly reduced linearity versus 5V but sufficient for many power-constrained base station modules. The LOBIAS pin allows further current reduction if needed, trading IIP3 for lower ICC.
Is MAX2044ETP+T pin-compatible with other Maxim mixers?
Yes, the MAX2044ETP+T is pin-similar to the MAX2039/MAX2041/MAX2042 family (1700–3000MHz) and the MAX2029/MAX2031 series (650–1000MHz). This enables common PCB layout across multiple frequency bands-reducing design time and qualification effort. However, RF/LO matching networks must be re-optimized per band; the pinout compatibility does not imply electrical drop-in replacement without tuning.
