Product details
Overview
MAX9996ETP+G48 from Maxim Integrated is a SiGe high-linearity downconversion mixer designed for UMTS/WCDMA, DCS, and PCS base-station receivers. It delivers 8.3dB conversion gain, +26.5dBm input IP3, 9.7dB noise figure, and operates with 1700–2200MHz RF and 1900–2400MHz LO frequencies in high-side injection architectures.
For engineers reviewing the MAX9996ETP+G48 datasheet, MAX9996ETP+G48 pinout, MAX9996ETP+G48 application, or MAX9996ETP+G48 equivalent, this page provides verified circuit role (RF-to-IF passive mixer with integrated LO buffer/switch), package mapping (20-pin thin QFN, 5mm × 5mm), thermal design guidance (exposed paddle), and real-world performance trade-offs across temperature and LO drive levels.
Technical Context
The MAX9996ETP+G48 implements a double-balanced passive mixer core driven by an on-chip two-stage LO buffer, enabling -3dBm to +3dBm LO drive while maintaining high linearity. Its integrated RF and LO baluns support single-ended 50Ω interfaces without external matching.
It features a built-in SPDT LO switch (43dB isolation, 50ns switching) and differential IF outputs (40–350MHz range), with bias currents set via external resistors (R1 = 806Ω, R2 = 549Ω). Performance is guaranteed over -40°C to +85°C with VCC = 4.75V–5.25V and ICC ≤ 240mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 1700–2200MHz: supports full UMTS/WCDMA, DCS1800, PCS1900 bands without retuning. |
| LO Frequency Range | 1900–2400MHz: optimized for high-side injection; enables fLO > fRF receiver topologies. |
| IF Frequency Range | 40–350MHz: accommodates standard IF stages including 200MHz typical for baseband processing. |
| Conversion Gain | 8.3dB typical: reduces need for post-mixer amplification, lowering system noise contribution. |
| IIP3 | +26.5dBm: ensures robust handling of strong adjacent-channel interferers in dense cellular environments. |
| Noise Figure | 9.7dB SSB: maintains receiver sensitivity under real-world blocking conditions (e.g., PRF = +5dBm). |
| LO Drive Range | -3dBm to +3dBm: simplifies LO source selection-no external amplifier required for most synthesizers. |
| Supply Current | ≤240mA at VCC = 5V: enables thermal management in compact multi-channel base station designs. |
Pinout & Package
The MAX9996ETP+G48 is housed in a 20-pin thin QFN package (5mm × 5mm) with exposed paddle (EP) for thermal and RF grounding. The package requires soldering the EP to the PCB ground plane using multiple vias.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,6,8,14 | VCC | Power supply inputs; each must be bypassed locally to GND for stable high-frequency operation. |
| 2 | RF | Single-ended 50Ω RF input; DC-short through internal balun-requires external DC-blocking capacitor. |
| 3 | TAP | Center tap of RF balun; must be bypassed to GND within 100 mils for optimal balun balance. |
| 4,5,10,12,13,17 | GND | Dedicated ground pins; routed directly to EP for low-inductance RF return path. |
| 7 | LOBIAS | Bias node for internal LO buffer; connects to VCC via 549Ω ±1% resistor to set LO drive level. |
| 9 | LOSEL | Digital control input: logic-low selects LO1, logic-high selects LO2; must be applied after VCC stabilization. |
| 11 | LO1 | First single-ended 50Ω LO input; internally matched-requires only 22pF DC-blocking capacitor. |
| 15 | LO2 | Second single-ended 50Ω LO input; identical interface to LO1, isolated by 43dB when unselected. |
| 16 | LEXT | External inductor connection (10nH); improves LO/RF-to-IF leakage; carries ~100mA DC current. |
| 18,19 | IF-, IF+ | Differential open-collector IF outputs; require external RF chokes to VCC for bias and impedance transformation. |
| 20 | IFBIAS | IF amplifier bias node; connects to GND via 806Ω ±1% resistor to set IF gain and current. |
| EP | GND | Exposed paddle; mandatory connection to PCB ground plane for thermal dissipation and RF stability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RF and LO baluns | Eliminates external baluns and matching networks-reduces BOM count and layout area for 50Ω single-ended interfaces. |
| On-chip SPDT LO switch | Enables frequency-hopping applications with 43dB LO1–LO2 isolation and sub-50ns switching-no external switch IC needed. |
| LO buffer with wide drive range | Accepts -3dBm to +3dBm LO input, relaxing synthesizer output power requirements and improving system-level power efficiency. |
| Differential IF outputs | Provides inherent 2LO-2RF rejection improvement and supports direct connection to differential ADCs or IF filters. |
| External bias resistors (R1/R2) | Allow fine-tuning of LO buffer and IF amplifier currents-enables trade-off between power consumption and linearity/noise performance. |
| Lead-free thin QFN package | 5mm × 5mm footprint with exposed paddle meets RoHS compliance and supports high-density RF board layouts. |
Applications
| UMTS/WCDMA Base Stations | DCS1800/PCS1900 EDGE Base Stations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar downconversion mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX9994 | LO range 1400–2000MHz; otherwise pin- and functionally compatible; optimized for low-side LO injection. | Preferred for fLO < fRF architectures (e.g., 1700MHz RF with 1800MHz LO); lower LO range trades off upper-band coverage. | Select MAX9994 when designing low-side injection receivers below 2000MHz LO-avoid for high-side above 2000MHz. |
| MAX9993 | Functionally compatible but not pin-compatible; lacks integrated LO switch and baluns; requires external matching. | Suitable for cost-sensitive designs where board space permits external components; no SPDT switching capability. | Choose MAX9993 only if LO switching and balun integration are unnecessary and external component count is acceptable. |
Compared with MAX9994 and MAX9993, the MAX9996ETP+G48 uniquely combines high-side LO optimization (1900–2400MHz), on-chip SPDT switching, and fully integrated baluns-making it the only option among the three that eliminates external LO/RF matching while supporting frequency-hopping in high-band base stations.

FAQ
What is the operating temperature range for the MAX9996ETP+G48?
The MAX9996ETP+G48 is specified to operate over an extended industrial temperature range of -40°C to +85°C. This range is defined at the exposed paddle (TC), which must be thermally coupled to the PCB ground plane. All electrical specifications-including conversion gain, IIP3, and noise figure-are guaranteed across this full range with VCC = 4.75V to 5.25V.
Does the MAX9996ETP+G48 require external baluns for RF and LO inputs?
No, the MAX9996ETP+G48 integrates on-chip RF and LO baluns, enabling direct connection of single-ended 50Ω sources to pins RF, LO1, and LO2. An external DC-blocking capacitor (e.g., 22pF) is still required at each port due to internal DC shorts, but no external transformers or matching networks are needed for basic operation.
How is the LO switching controlled on the MAX9996ETP+G48?
LO switching on the MAX9996ETP+G48 is controlled by the LOSEL pin (Pin 9): applying logic-low selects LO1 (Pin 11), and logic-high selects LO2 (Pin 15). The switch achieves 43dB isolation between LO inputs and settles in under 50ns. Voltage must be applied to VCC before asserting LOSEL to prevent damage, as specified in the Absolute Maximum Ratings.
What are the recommended bias resistors for the MAX9996ETP+G48?
The MAX9996ETP+G48 requires two precision external resistors: an 806Ω ±1% resistor from IFBIAS (Pin 20) to GND sets IF amplifier bias, and a 549Ω ±1% resistor from LOBIAS (Pin 7) to VCC sets LO buffer drive level. Standard ±5% resistors may be substituted if ±1% parts are unavailable, though performance may vary slightly.
Can the MAX9996ETP+G48 be used in low-side LO injection configurations?
Yes, the MAX9996ETP+G48 supports low-side LO injection (fLO < fRF) within its 1900–2400MHz LO range, but performance degrades as fLO decreases below 2000MHz. For dedicated low-side applications-especially below 2000MHz-the MAX9994 variant is optimized and recommended, as it is tuned for 1400–2000MHz LO operation and delivers superior linearity in that range.
