Product details

Overview

MLPF-NRG-01D3 from STMicroelectronics is a 2.4 GHz integrated low-pass filter with impedance matching network and harmonic rejection, designed for RF front-end integration between STM32WB0 series and BLUENRG-LP-LPS (BLUENRG-3x5Vx/3x5Ax/332xx) SoCs and antennas. It delivers 1.1 dB typical insertion loss, 50 Ω antenna-side impedance, ≥31 dB harmonic attenuation at 2f₀, and operates across –40 °C to +105 °C in Bluetooth 5 and IEEE 802.15.4 systems.

For engineers reviewing the MLPF-NRG-01D3 datasheet, MLPF-NRG-01D3 pinout, MLPF-NRG-01D3 application, or MLPF-NRG-01D3 equivalent, this component enables rapid RF layout validation with pre-matched 57 Ω input and 50 Ω output impedances, verified harmonic suppression up to 5f₀, and CSPG package compatibility with QFN/CSP-based wireless MCUs.

Technical Context

This device implements a monolithic IPD (Integrated Passive Device) structure on non-conductive glass substrate, enabling precise impedance transformation from the SoC's 57 Ω single-ended RF output to a standard 50 Ω antenna interface while maintaining deep harmonic rejection. Its architecture integrates both matching and filtering functions in one passive die, eliminating discrete baluns, capacitors, and inductors.

The filter targets fundamental 2400–2500 MHz operation with measured S₂₁ insertion loss ≤1.1 dB and S₁₁/S₂₂ return losses ≥11 dB and ≥12 dB respectively - ensuring minimal signal reflection at both ports. Harmonic attenuation exceeds 31 dB at 4800–5000 MHz (2f₀), 42 dB at 7200–7500 MHz (3f₀), and remains >32 dB through 5f₀, meeting stringent ETSI/FCC spectral mask requirements.

Pin/Terminal	Circuit Role	Design Meaning
IN	RF input	Connects directly to RF output of STM32WB0 or BLUENRG-LP-LPS SoC (57 Ω matched).
OUT	RF output	Drives 50 Ω antenna trace or chip antenna; requires controlled-impedance routing.
GND1–GND4	Ground terminals	Four dedicated ground bumps ensure low-inductance RF return path and minimize ground loop radiation.

Key Features

Feature	Design Value
Integrated impedance matching	Pre-tuned 57 Ω → 50 Ω transformation eliminates need for external matching components and layout iterations.
Deep harmonic rejection	≥31 dB attenuation at 2f₀ and ≥42 dB at 3f₀ ensures compliance with global regulatory spectral masks.
Low-profile CSPG package	≤630 μm height enables ultra-thin wearable and space-constrained IoT designs without sacrificing RF performance.
IPD-on-glass technology	Enables high-Q passive elements and tight tolerance matching unattainable with PCB-based or LTCC solutions.
ECOPACK2 compliance	Meets RoHS, REACH, and halogen-free requirements for sustainable electronics manufacturing.

FAQ

What is the recommended PCB stack-up for optimal RF performance?

The datasheet specifies a 2-layer evaluation board with ground plane on L1 (directly under the device) and reference ground on L2. Dielectric thickness must be 0.500–1.600 mm and Dk between 3.6–4.9. Drill density under the device must be maximized to maintain equipotentiality and minimize ground inductance.

Can MLPF-NRG-01D3 be used with non-ST 2.4 GHz SoCs?

No - its impedance network is specifically optimized for STM32WB0 series and BLUENRG-LP-LPS SoCs in QFN/CSP packages. Input impedance is tuned to 57 Ω, not standard 50 Ω, and harmonic rejection profile aligns with those SoCs' fundamental and harmonic spectra.

Is a matching network required between MLPF-NRG-01D3 and the antenna?

No - the OUT terminal is designed for direct connection to a 50 Ω antenna trace or chip antenna. The device provides full 50 Ω output impedance matching; adding external components degrades insertion loss and return loss performance.

What reflow profile should be used during assembly?

ST recommends a peak reflow temperature of 240–245 °C for 2–3 seconds, with ramp rates ≤3 °C/s pre-peak and ≤2 °C/s post-peak. Air convection must be minimized to prevent component shift. Full profile details are in Figure 16 of DS14044 Rev 5.
