Telecom & RF Shielding
High-frequency shielding for 5G infrastructure, base stations, and wireless systems. Optimized for mmWave performance.
Telecommunications equipment operates across an increasingly congested spectrum, from sub-6 GHz to mmWave frequencies. Effective RF shielding is essential for signal integrity, regulatory compliance, and coexistence with adjacent systems.
POCONS provides RF shielding solutions optimized for modern telecommunications applications, including 5G NR, small cells, and satellite communications.
5G Infrastructure Equipment
5G networks operate across multiple frequency bands with unique shielding requirements:
- Sub-6 GHz radios require traditional RF isolation techniques
- mmWave equipment (24-47 GHz) demands precision shielding with minimal apertures
- Massive MIMO systems need isolation between antenna elements
The aperture math is unforgiving at these frequencies. An opening starts to leak once its longest dimension approaches λ/20: at 28 GHz (λ ≈ 10.7 mm) that is about 0.5 mm, and at 39 GHz (λ ≈ 7.7 mm) under 0.4 mm. mmWave shields therefore need tight-tolerance stamping, dense clip and spring-finger pitch to keep effective seam lengths short, and honeycomb vents — the same open area split into many electrically-small holes — rather than open slots.
Our high-frequency shield designs minimize signal leakage at mmWave frequencies while maintaining thermal management for high-power applications.

Base Station & Small Cell
Base stations and small cells combine multiple radios and processing elements:
- RF front-ends require isolation from digital switching noise
- Power amplifiers generate significant harmonic content
- Baseband processors need protection from RF ingress
POCONS provides robust shielding solutions designed for outdoor deployment environments with wide temperature ranges.

Antenna & RF Module Shielding
Integrated antenna modules require careful RF management:
- Transmit/receive isolation prevents desensitization
- Inter-band isolation enables carrier aggregation
- LNA protection from high-power transmit signals
Our shield designs support the close integration of antennas and RF electronics in modern wireless systems.

Network Infrastructure
Core network equipment processes high-speed digital signals:
- Routers and switches generate broadband emissions from high-speed SerDes
- Optical transceivers require isolation from adjacent digital circuits
- Timing equipment needs protection from electromagnetic interference
POCONS provides board-level shielding that addresses both emissions and immunity requirements for network infrastructure.

US-Built 5G & Network Gear That Uses Board-Level Shields Like These
Domestic 5G radio production and network infrastructure are shielding-intensive. RF radio units and high-speed line cards built in the US use board-level shields to control emissions (FCC Part 15) and protect RF front ends.
POCONS shield components are manufactured in Korea (IATF 16949) and stocked and supported domestically from San Diego. The end products above are US-built and use this class of board-level shielding; this page does not claim any specific named product contains POCONS parts.
US-built products & board-level shielding
Why do US-made 5G radios use board-level shielding?
RF radio units pack power amplifiers, transceivers, and digital logic close together. Board-level shield cans isolate the RF front end, suppress harmonics, and are essential to meet FCC Part 15 and CISPR emissions limits.
Does buying domestically shorten lead time for 5G hardware shields?
Sourcing from a domestically-stocked, US-supported supplier avoids broker markup and overseas tooling cycles — POCONS stocks and supports parts from San Diego and can tool custom RF cavities quickly.

Frequently Asked Questions
Can your shields handle 5G mmWave frequencies (24–40 GHz)?
Yes, but at mmWave the aperture and seam limit tightens sharply: the λ/20 rule puts the largest safe opening in the sub-millimetre range (about 0.5 mm at 28 GHz for ~20 dB). We tool tight-tolerance cans with dense clip/finger pitch to keep effective seam lengths short.
What shielding do you offer for base stations and small cells?
Board-level shield cans, fences, and covers — often multi-cavity to isolate RF front-ends from digital and power sections within dense base-station and small-cell boards.
Why does vent and clip-pitch design matter more at high frequency?
Leakage scales with the longest opening dimension versus wavelength, and wavelength shrinks with frequency. At RF/mmWave you must use arrays of small vent holes (honeycomb/perforation) and tight contact pitch rather than a few large openings.
Where are the telecom parts manufactured?
Precision-stamped at our IATF 16949–certified facility in Korea, with sales, stock, custom tooling, and engineering support from POCONS USA in San Diego. We do not represent the parts as US-made.
