Product details
Overview
The MAX19996AETP+ from Maxim Integrated is a SiGe high-linearity downconversion mixer designed for wireless infrastructure receivers operating from 2000MHz to 3900MHz RF, with 2100MHz–4000MHz LO and 50MHz–500MHz IF ranges. It delivers 8.7dB conversion gain, +24.5dBm IIP3, and 9.8dB noise figure at 2600MHz/300MHz under 5V supply, enabling robust signal extraction in LTE, WiMAX, and MMDS base stations.
For engineers reviewing the MAX19996AETP+ datasheet, MAX19996AETP+ pinout, MAX19996AETP+ application, or MAX19996AETP+ equivalent, this page provides verified RF performance metrics, thermal behavior across –40°C to +85°C, single-ended interface support via integrated baluns, and pin-compatibility guidance with legacy mixers for multi-band PCB reuse.
Technical Context
The MAX19996AETP+ implements a double-balanced passive mixer core with on-chip RF and LO baluns, eliminating external transformers for single-ended RF/LO drive. Its LO buffer supports low–3dBm to +3dBm drive, enabling direct connection to PLL synthesizers without amplification.
It operates in both high-side (fRF < fLO) and low-side (fRF > fLO) injection modes across its full RF/LO bands, with measured 2LO-2RF spur rejection up to 90dBc and 3LO-3RF up to 85dBc-critical for adjacent-channel interference suppression in dense spectrum deployments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 2000MHz–3900MHz: Covers WCS, LTE Bands 7/38/41, WiMAX 2.5/3.5GHz, and MMDS 2.7GHz systems. |
| LO Frequency Range | 2100MHz–4000MHz: Enables flexible high-side or low-side injection without external frequency translation. |
| IF Frequency Range | 50MHz–500MHz: Supports standard IF architectures including 300MHz and 450MHz with external transformer tuning. |
| Conversion Gain | 8.7dB typical: Reduces need for post-mixer amplification, lowering system noise figure and power consumption. |
| IIP3 | +24.5dBm typical: Ensures strong two-tone linearity in crowded base station environments with co-located transmitters. |
| Noise Figure | 9.8dB SSB NF at 2600MHz: Maintains receiver sensitivity despite wideband operation and integrated IF amplification. |
| Supply Current | 230mA @ 5V or 150mA @ 3.3V: Enables dual-voltage design flexibility and thermal management in compact RF modules. |
Pinout & Package
The MAX19996AETP+ is housed in a 5mm × 5mm, 20-pin thin QFN with exposed pad (EP), optimized for RF thermal dissipation and board-level EMI control.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Power supply input | Accepts 3.3V or 5.0V; decoupling required per layout guidelines to suppress supply noise coupling into RF path. |
| GND | Ground reference | Multiple dedicated pins (1, 4, 7, 10, 13, 16, 19, 20) plus EP ensure low-inductance return paths for RF/LO/IF sections. |
| RF | Radio-frequency input | Single-ended port with integrated balun; 50Ω match enables direct connection to antenna front-end filters. |
| LO | Local oscillator input | Single-ended port with integrated balun; accepts –3dBm to +3dBm drive, simplifying synthesizer interface. |
| IF+ | Differential IF output positive | DC-coupled differential output; requires external 200Ω termination and transformer for 50Ω single-ended IF routing. |
| IF– | Differential IF output negative | Paired with IF+; differential signaling improves common-mode noise rejection in noisy base station environments. |
| EN | Enable control | Active-high digital input; allows power-gating during idle periods to reduce system standby current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RF and LO baluns | Eliminates discrete 4:1 transformers, reducing BOM count, board area, and impedance mismatch risk in production RF layouts. |
| Pin compatibility with MAX19996 | Enables drop-in upgrade from 2000–3000MHz variant without PCB revision, accelerating multi-band platform development. |
| Ultra-wide LO range (2100–4000MHz) | Supports single hardware design across 2.5GHz and 3.5GHz infrastructure bands using identical LO synthesis architecture. |
| Low LO drive requirement (–3 to +3dBm) | Permits direct interface with low-power fractional-N PLLs, avoiding costly LO buffer stages and associated phase noise degradation. |
| External current-setting resistors | Allows trade-off between supply current (150–230mA) and linearity/noise performance for thermal-constrained applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar downconversion mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX19996ETP+ | 2000–3000MHz RF range; identical pinout and package; lower upper RF limit excludes 3.5GHz WiMAX. | Limited to sub-3GHz infrastructure; unsuitable for 3.1–3.9GHz licensed bands. | Select when only 2.3–2.7GHz WCS/LTE coverage is required and cost optimization is prioritized. |
| MAX9994ETP+ | 1700–2200MHz RF range; pin-similar but not pin-compatible; requires PCB layout adjustment. | Targets AWS and PCS bands; incompatible with 2.5/3.5GHz systems without redesign. | Choose for legacy 1.9GHz PicoCell upgrades where existing MAX9994 footprint reuse is possible. |
Compared with the MAX19996ETP+, the MAX19996AETP+ extends RF coverage to 3900MHz while retaining pin compatibility-enabling seamless migration to higher bands. Against the MAX9994ETP+, it shifts operational focus upward by 800MHz, requiring new RF matching but delivering superior IIP3 (+24.5dBm vs. +22.5dBm) in its target band.

FAQ
What is the guaranteed operating temperature range for the MAX19996AETP+?
The MAX19996AETP+ is specified for continuous operation from –40°C to +85°C case temperature, with electrical performance fully characterized across this range. The exposed pad thermal design must maintain junction temperature below +150°C per absolute maximum ratings, and thermal resistance θJC is 13°C/W.
Does the MAX19996AETP+ require external baluns for RF and LO inputs?
No, the MAX19996AETP+ integrates on-chip baluns for both RF and LO ports, enabling true single-ended 50Ω interfaces. This eliminates the need for external Mini-Circuits TC4-1W-17 or similar transformers, reducing component count and layout complexity while maintaining >17.5dB RF input return loss.
Can the MAX19996AETP+ operate with a 3.3V supply, and how does performance change?
Yes, the MAX19996AETP+ supports 3.3V operation with 150mA typical supply current. At 3.3V, conversion gain remains 8.2–9.5dB, IIP3 is +22–+24.05dBm, and NF is 9.5–10.5dB-slightly reduced linearity versus 5V mode but sufficient for many low-power remote radio units and small cells.
Is the MAX19996AETP+ pin-compatible with the MAX19996 2000–3000MHz mixer?
Yes, the MAX19996AETP+ is explicitly documented as pin-compatible with the MAX19996 2000–3000MHz mixer. Identical pinout, package (20-pin thin QFN-EP), and footprint allow direct replacement without PCB modification-ideal for upgrading existing 2.3–2.7GHz designs to cover 3.5GHz bands.
What LO drive level is required for optimal performance of the MAX19996AETP+?
The MAX19996AETP+ is optimized for –3dBm to +3dBm LO drive, with 0dBm delivering best-in-class IIP3 (+24.5dBm) and NF (9.8dB). Drive outside this range degrades linearity and noise performance; no external LO amplifier is needed when paired with standard fractional-N synthesizers.
