Coexistence & Mechanical Footprint Challenges

Consumer expectations for sleek, minimalist Wi-Fi pods force industrial designers to shrink enclosures while cramming multiple multi-gigabit LAN ports.

RF & ENCLOSURE BOTTLENECK

The RF Desense Dilemma

When 2.5GBase-T Ethernet ports operate adjacent to high-gain Wi-Fi 6/7 MIMO antennas, high-frequency PHY clock harmonics radiate into radio receivers.

▸

Wi-Fi Throughput Collapse (Desense):Clocks at 125MHz/250MHz and their harmonics bleed into 2.4GHz and 5.8GHz channels, reducing Wi-Fi sensitivity by 6dB~12dB.

▸

Strict Enclosure Height Caps:Mesh nodes and smart wall pads under 20mm thickness cannot physically accommodate standard 13.5mm RJ45 connectors.

▸

Standby Energy Mandates:European EuP Lot 6 and Energy Star require ultra-low idle standby power dissipation.

RF MITIGATION & CO-DESIGN

Our Acoustic & RF Engineered Solution

We deploy mid-mount (sinking PCB) mechanical designs coupled with custom notch-filter magnetics to achieve harmonious coexistence.

✓

Sinking Mid-Mount RJ45:Sits flush into PCB cutouts, lowering the above-board profile to just 9.5mm to 10.5mm.

✓

Harmonic Trap Notch Magnetics:Custom internal common-mode choke cores suppress radiated emissions in the 2.4GHz to 6GHz bands by over 40dB.

✓

Multi-Point Shell Grounding:Multiple chassis grounding spring tabs bond firmly to enclosure metalwork, preventing floating ground radiation.
