5G radios pack more RF power into smaller, denser hardware than any generation before them — and that density creates interference problems that mechanical design alone can't solve. 3G Shielding Specialties supplies Wavexorb microwave absorbers, Waveseal conductive gaskets and board level shields to telecom OEMs building base stations, small cells and mmWave hardware — with free 48-hour samples and same-business-day engineering answers.

Where Shielding & Absorbers Fit in 5G Hardware

• Massive MIMO / active antenna units — cavity resonance absorbers suppress oscillations and resonant modes inside shielded RF cavities from 1–20 GHz.
• Remote radio heads & outdoor small cells — conductive elastomer gaskets provide combined EMI and environmental sealing on weather-exposed housings.
• Baseband units (BBU/gNodeB) — MULTIZONE multi-cavity board level shields isolate transceiver, processor and power sections on one dense PCB.
• mmWave (FR2) front-end modules — HYBRID shields deliver machined-housing performance at a fraction of the cost for 24 GHz+ designs.
• Antenna structures & radomes — surface wave absorbers attenuate traveling waves on conductive surfaces; broadband dielectric foam handles free-space absorption.
• Test fixtures & OTA chambers — carbon-loaded foam absorbers reduce reflections during radio qualification and production test.

Matching Materials to 5G Frequency Ranges

Gaskets for Outdoor Telecom Enclosures

Outdoor radios and street-level small cells need gaskets that seal against weather while maintaining shielding performance over thousands of thermal cycles. Waveseal fabric-over-foam offers low closure force for large door seals; conductive elastomers combine EMI shielding with environmental (IP) sealing on flange joints; and Cu/Ni conductive fabric and tape provide an economical wrap or seam fix. For material trade-offs, see our EMI gasket materials comparison.

Why Telecom OEMs Work With 3G

• Absorber depth — narrowband, cavity-resonance, surface-wave, low-frequency and broadband foam formulations under one roof, custom die-cut with adhesive backing.
• Short lead times — US-based manufacturing keeps prototype and production schedules on track.
• ISO 9001:2015 quality system, serving telecom, aerospace and industrial OEMs since 1994.
• Free 48-hour samples — evaluate materials in your own hardware before committing.

Telecom & 5G Shielding FAQs

How do I stop cavity resonance inside a board level shield?

Bond a cavity resonance absorber to the inside of the shield lid. Wavexorb cavity resonance materials attenuate oscillations and harmonics from 1–20 GHz at normal and high angles of incidence, without redesigning the shield.

Do absorbers work at mmWave (FR2) frequencies?

Yes. Absorber formulation is frequency-dependent — narrowband materials can be tuned to a target band, and our engineers will match a formulation to your 24 GHz+ application.

Can 3G supply die-cut absorber parts with adhesive?

Yes. Wavexorb absorbers are supplied as custom die-cut parts, most with pressure-sensitive adhesive backing, ready for placement in production.

How quickly can we test materials in our radio?
