Product details
Overview
MAX2042AETP+ from Maxim Integrated is a SiGe high-linearity upconversion/downconversion mixer IC designed for RF front-end signal translation in wireless infrastructure. It delivers +33dBm input IP3, 7.25dB noise figure, and 7.2dB conversion loss across 1600MHz–3900MHz RF, supporting GSM/EDGE, WCDMA, LTE, TD-LTE, WiMAX, and MMDS base stations.
For engineers reviewing the MAX2042AETP+ datasheet, MAX2042AETP+ pinout, MAX2042AETP+ application, or MAX2042AETP+ equivalent, key selection criteria include its ultra-wide 1300MHz–4000MHz LO range, integrated LO buffer and baluns for single-ended drive, dual supply compatibility (3.3V/5.0V), and guaranteed performance from –40°C to +85°C in compact TQFN packaging.
Technical Context
The MAX2042AETP+ implements a double-balanced passive mixer core with on-chip RF and LO baluns, enabling true single-ended RF and LO interface without external transformers. Its architecture supports both high-side and low-side LO injection across multiple RF bands via external tuning components (e.g., C1/L1 variants).
It integrates an LO buffer delivering stable gain and isolation, reducing external driver requirements. The differential IF ports operate at nominal 50Ω impedance and support 50MHz–500MHz bandwidth, with RF-to-IF isolation exceeding 35dB and spurious rejection (e.g., 2LO–2RF) up to 83dBc under defined conditions.
Key Specifications

| IF Frequency Range | 50MHz to 500MHz - supports standard IF architectures including 300MHz and 450MHz downconversion paths |
| Input IP3 | +33dBm - ensures robust linearity against adjacent-channel interference in dense multi-carrier base stations |
| Noise Figure | 7.25dB (typical, 5V) - maintains receiver sensitivity in high-gain front-end designs |
| Conversion Loss | 7.2dB (typical, 5V, 2600MHz) - defines minimum required IF gain budget for system SNR planning |
| Supply Voltage | 3.3V or 5.0V - allows direct integration into legacy 5V or modern low-voltage RF subsystems |
| Operating Temperature | –40°C to +85°C - qualified for outdoor macro/micro base station enclosures and industrial environments |
Pinout & Package
The MAX2042AETP+ is housed in a 20-pin TQFN package (5mm × 5mm) with exposed thermal pad, optimized for RF performance and thermal dissipation in high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Positive supply input | Accepts 3.3V or 5.0V; bypassing required per datasheet for RF stability |
| GND | Ground reference | Multiple pins (1, 4, 7, 10, 13, 16, 19) - must be low-inductance connection to exposed pad |
| RF | RF port (single-ended) | 1600–3900MHz signal path; internal balun converts to differential mixer core |
| LO | LO port (single-ended) | 1300–4000MHz local oscillator input; buffered and balanced internally |
| IF+, IF– | Differential IF outputs/inputs | 50Ω nominal differential impedance; requires external transformer for single-ended IF interface |
| LOBIAS | LO bias control | Adjusts LO buffer current; sets LO drive level and power consumption trade-off |
| EXPOSED PAD | Thermal & RF ground | Must be soldered to solid copper pour for thermal management and RF return path integrity |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LO buffer | Eliminates need for external LO amplifier; accepts –6dBm to +3dBm drive, simplifying LO chain design |
| On-chip RF and LO baluns | Enables fully single-ended RF/LO interface - reduces BOM count and layout area vs. discrete balun solutions |
| PIN-compatible with MAX2042 | Direct replacement for 2000–3000MHz variant; allows frequency-band scaling on same PCB layout |
| Reduced-power mode | External resistor on LOBIAS pin lowers ICC (e.g., 122mA @ 3.3V), enabling thermal/power optimization |
| Wideband spurious suppression | 72dBc typical 2LO–2RF rejection at PRF = –10dBm - improves dynamic range in crowded spectral environments |
| Single-supply operation | Operates from either 3.3V or 5.0V rail - avoids dual-supply complexity in mixed-signal RF subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2042ETP+ | 2000–3000MHz RF range; identical pinout and package; lower upper-frequency limit | Optimized for 2.0–3.0GHz only; not suitable for 3.5GHz WiMAX or 3.9GHz LTE-U | Select when targeting narrowband 2.1GHz/2.6GHz systems where MAX2042AETP+ over-specification adds cost |
| MAX2044ETP+ | 2300–4000MHz RF range; pin-similar but not pin-compatible; different pin mapping | Higher RF upper limit (4.0GHz); requires PCB redesign due to altered pin functions and layout | Choose for 3.5–4.0GHz mmWave-adjacent systems where MAX2042AETP+'s 3.9GHz ceiling is insufficient |
Compared with MAX2042ETP+, the MAX2042AETP+ extends RF coverage to 3.9GHz while retaining drop-in compatibility for 2.0–3.0GHz designs; versus MAX2044ETP+, it offers verified pin compatibility but trades 100MHz upper-band margin for layout reuse across multi-band platforms.

FAQ
What is the maximum RF frequency supported by the MAX2042AETP+?
The MAX2042AETP+ supports RF frequencies up to 3900MHz, validated across multiple configurations including high-side and low-side LO injection modes. At 3500MHz with low-side LO (3200MHz), it achieves 8.2dB conversion loss and 71dBc 2RF–2LO spur rejection. This 1600–3900MHz range covers all major licensed bands from 1.8GHz through 3.5GHz WiMAX and LTE.
Does the MAX2042AETP+ require external baluns for RF and LO inputs?
No, the MAX2042AETP+ integrates on-chip RF and LO baluns, enabling direct single-ended connection of 50Ω RF and LO sources. This eliminates discrete baluns or transformers in most implementations, reducing bill-of-materials cost and PCB area. External matching components (e.g., C1/L1 per Table 1) are still required for optimal band-specific return loss.
Can the MAX2042AETP+ operate from a 3.3V supply?
Yes, the MAX2042AETP+ is fully specified for 3.3V operation, drawing 122mA typical supply current. At 3.3V, it delivers 7.4dB conversion loss and 7.4dB noise figure (2600MHz, high-side LO), with +31dBm IIP3 - slightly reduced versus 5V operation but sufficient for many low-power remote radio head and small-cell applications.
Is the MAX2042AETP+ pin-compatible with other Maxim mixers?
Yes, the MAX2042AETP+ is pin-compatible with the MAX2042 (2000–3000MHz) and pin-similar with the MAX2039/MAX2041 (1700–3000MHz) and MAX2029/MAX2031/MAX2033 (650–1550MHz). This enables common PCB footprint reuse across multiple frequency bands, accelerating multi-band radio development and reducing NRE costs.
What is the function of the LOBIAS pin on the MAX2042AETP+?
The LOBIAS pin on the MAX2042AETP+ sets the bias current of the integrated LO buffer. Connecting an external resistor between LOBIAS and GND allows adjustment of LO drive strength and supply current - enabling reduced-power mode operation (e.g., lowering ICC from 140mA to ~100mA at 5V) while maintaining adequate LO output for mixer switching.
