Where our boards power
the connected world

Modern telecommunications infrastructure demands RF performance that standard PCB materials simply cannot deliver. We specialise in the boards that make it possible.

01

5G mmWave Beamforming Antennas

Hybrid Rogers 4350B / FR4 boards with cavity-milled patch apertures and TDR-verified impedance on 100+ antenna feed lines for massive MIMO array modules.

02

Base Station Radio Units

12- to 20-layer hybrid RF/digital multilayer boards combining RF-grade outer layers with FR4 cores for cost-optimised 28/39 GHz small cell and macro radio electronics.

03

RF Power Amplifier Boards

Thermal-via-array and embedded-coin constructions dissipating hundreds of watts per board, keeping junction temperatures in spec on high-power 5G PA modules.

04

Data Centre Switch Backplanes

20- to 30-layer sequential lamination boards with back-drilled vias and ENEPIG press-fit finish, routing 112 Gbps PAM4 lanes for 400G/800G line cards.

05

Satellite Ku/Ka-Band Transceivers

16-layer Taconic TLY low-loss laminate boards with gold-plated RF connectors for LEO and GEO satellite transceiver modules qualified to thermal vacuum standards.

06

Optical Transceiver Modules

Controlled-impedance HDI boards on Rogers RO4003C with tight ±0.5 mil trace tolerance, supporting high-speed electrical-to-optical signal conversion in pluggable modules.

07

Network Switch Line Cards

Sequential-lamination backplanes up to 30 layers with dozens of differential-pair structures, routed to eliminate crosstalk and modal resonance across the chassis.

08

Fixed Wireless Access Terminals

Hybrid Rogers/FR4 multilayer boards with TDR/VNA-verified ±5% impedance, packing sub-6 GHz and mmWave radios into compact outdoor CPE enclosures.

The Engineering Challenge

Why telecom PCBs demand
specialist RF expertise

At millimetre-wave frequencies, the PCB is no longer just a circuit carrier — it is an active part of the RF system. Material choice, trace geometry and fabrication tolerance directly affect signal performance.

01

Signal Integrity at mmWave Frequencies

At 28 GHz, 39 GHz and 77 GHz, dielectric loss in standard FR4 renders the board electrically invisible to the RF signal. Rogers, Taconic and PTFE-based laminates are mandatory. Trace width tolerance must be held to ±0.5 mil to maintain consistent impedance within ±5%.

02

High-Layer-Count Signal Management

Modern network switches and base station radio units require 20–30 layer boards with dozens of controlled impedance structures — differential pairs, coplanar waveguides and microstrip lines — all routed without crosstalk or modal resonance.

03

Thermal Management in High-Power RF

5G power amplifier boards dissipate hundreds of watts per board in compact form factors. Thermal vias, embedded coin cooling and back-side thermal pads must be designed and fabricated to tight tolerances to keep junction temperatures within spec.
