Product details
Overview
MAX2029ETP+ from Maxim Integrated is a high-linearity passive upconverter/downconverter mixer designed for GSM/cellular base-station transmitters and receivers. It delivers +36.5dBm IIP3 (downconversion), 6.7dB noise figure, 6.5dB conversion loss, operates across 815–1000MHz RF and 570–900MHz LO bands, and integrates on-chip baluns, LO buffer, and SPDT LO switch.
For engineers reviewing the MAX2029ETP+ datasheet, MAX2029ETP+ pinout, MAX2029ETP+ application, or MAX2029ETP+ equivalent, this page provides verified RF/IF/LO performance data, thermal and supply specifications, functional pin definitions, and validated alternatives for cellular infrastructure design.
Technical Context
The MAX2029ETP+ implements a double-balanced passive mixer core with integrated single-ended RF and dual LO baluns, enabling direct 50Ω interfacing without external matching. Its internal SPDT LO switch supports frequency-hopping architectures with 53dB isolation and 50ns switching time, controlled by LOSEL logic input.
Optimized for low-side LO injection (fLO < fRF), it achieves stable downconversion performance over -40°C to +85°C with guaranteed 6.5dB conversion loss and ±0.4dB flatness across 920–960MHz. Upconversion mode yields 6dB loss and +39dBm IIP3, with differential IF port supporting both modes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 815–1000 MHz - Supports full GSM 850/900, WCDMA, cdma2000 base-station bands in one device. |
| LO Frequency Range | 570–900 MHz - Optimized for low-side injection; enables compact local oscillator design with minimal filtering. |
| IF Frequency Range | DC–250 MHz - Accommodates baseband, low-IF, and zero-IF receiver architectures with differential IF interface. |
| Conversion Loss | 6.5 dB (downconvert), 6 dB (upconvert) - Low loss preserves signal-to-noise ratio in cascaded RF chains. |
| IIP3 | +36.5 dBm (downconvert), +39 dBm (upconvert) - Enables high dynamic range in multi-carrier cellular transceivers. |
| Noise Figure | 6.7 dB (SSB) - Meets stringent sensitivity requirements for cellular base-station receivers. |
| LO Drive Requirement | -3 to +3 dBm - Reduces need for external LO amplification; compatible with low-power synthesizers. |
| Supply Current | ≤100 mA at VCC = 5V - Enables efficient power budgeting in multi-channel RF front-ends. |
Pinout & Package
MAX2029ETP+ uses a 20-pin thin QFN package (5mm × 5mm) with exposed paddle for thermal dissipation. Pin functions are defined per Maxim's official pin configuration diagram and absolute maximum ratings table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 6, 8, 14 | VCC | Power supply input (4.75–5.25V); each requires local bypass capacitor to GND for RF stability. |
| 2 | RF | Single-ended 50Ω RF port - used as input (downconvert) or output (upconvert); DC shorted to GND via internal balun. |
| 3 | TAP | Center tap of internal RF balun - not externally connected; internal node only. |
| 4 | LOBIAS | LO bias control - sets LO buffer current; connects to external resistor for reduced-power mode. |
| 5, 17, 19 | GND | Ground terminals - must be soldered to PCB ground plane; exposed paddle is primary thermal path. |
| 7, 9, 10, 12, 13, 16, 18, 20 | GND | Additional ground pins - ensure low-inductance return paths for RF/LO/IF signals and supply decoupling. |
| 11 | LOSEL | Digital LO select input - logic-low selects LO1, logic-high selects LO2; must be driven only after VCC applied. |
| 15 | LO1 | First single-ended LO input - 50Ω matched; selected when LOSEL = low. |
| 19 | LO2 | Second single-ended LO input - 50Ω matched; selected when LOSEL = high. |
| IF+ | Differential IF output (downconvert) / input (upconvert) | True differential interface - improves IIP2, reduces even-order distortion, and enables transformerless connection to ADCs or modulators. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated RF and LO baluns | Eliminates external baluns and matching networks - reduces BOM count and board area in dense RF layouts. |
| Built-in SPDT LO switch | 53dB LO1–LO2 isolation and 50ns switching time - enables fast frequency hopping without external switches or relays. |
| On-chip LO buffer | Accepts -3 to +3dBm LO drive - relaxes requirements on LO source power and simplifies synthesizer selection. |
| Dual-mode operation | Same pinout and biasing for upconversion and downconversion - allows reuse of PCB layout across transmit/receive paths. |
| External current-setting resistor | Adjusts LO buffer current to trade off linearity vs. power consumption - supports flexible thermal/power optimization. |
| Lead-free 20-pin thin QFN | 5mm × 5mm footprint with exposed paddle - meets RoHS requirements and provides 13°C/W junction-to-case thermal resistance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar passive mixer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2031 | Optimized for 960–1180MHz LO range; higher LO frequency capability but lower IIP3 (+33dBm typical). | Preferred for high-side LO injection where fLO > fRF; not drop-in compatible due to different LO range and pin function mapping. | Select MAX2031 only when high-side LO architecture is required and LO frequency exceeds 900MHz. |
| MAX2041 | 1700–2200MHz RF range; identical pinout and package but shifted frequency coverage; same LO buffer/switch architecture. | Designed for PCS/UMTS bands; cannot replace MAX2029ETP+ in 815–1000MHz applications without RF redesign. | Use MAX2041 for multi-band systems sharing PCB layout across frequency bands - requires separate RF matching network. |
Compared with MAX2031 and MAX2041, the MAX2029ETP+ uniquely balances 815–1000MHz RF coverage, +36.5dBm IIP3, and low-side LO optimization - making it the only validated choice for GSM 850/900 base-station receivers requiring minimal external components.

FAQ
What is the operating temperature range for the MAX2029ETP+?
The MAX2029ETP+ is specified for continuous operation from -40°C to +85°C ambient temperature, with electrical performance guaranteed across this extended industrial range. Junction temperature must not exceed +150°C, and thermal design should account for θJC = +13°C/W using the exposed paddle as the primary heat path.
Does the MAX2029ETP+ require external baluns for RF or LO interfaces?
No - the MAX2029ETP+ integrates on-chip baluns for both RF and LO ports, enabling direct 50Ω single-ended connections without external transformers or matching networks. The RF port is internally DC-shortened to GND through the balun, so an external DC-blocking capacitor is required.
Can the MAX2029ETP+ be used in high-side LO injection architectures?
The MAX2029ETP+ is optimized for low-side LO injection (fLO < fRF) and performs best within its specified 570–900MHz LO range. While operation with fLO up to 1000MHz is possible, performance degrades - especially IIP3 and conversion loss - making the MAX2031 the recommended alternative for true high-side LO designs.
What is the purpose of the LOSEL pin on the MAX2029ETP+?
The LOSEL pin controls the internal SPDT LO switch: logic-low selects LO1, logic-high selects LO2. It enables frequency-hopping between two independent LO sources with 53dB isolation and <50ns settling time. Voltage must be applied to VCC before asserting LOSEL to avoid damage per Absolute Maximum Ratings.
How does the MAX2029ETP+ achieve low LO drive sensitivity?
The MAX2029ETP+ incorporates an integrated LO buffer that amplifies the input signal to drive the passive mixer core efficiently. This allows operation with only -3dBm to +3dBm LO input power - significantly lower than typical passive mixers - reducing synthesizer output power requirements and system-level power consumption.
