Service 03 · RF & antenna design

RF and antenna design services for real-world systems.

We design and tune microwave antennas and systems, including complex mixed-signal PCB assemblies. We build matching networks, RF frontends, filters, amplifiers and troubleshoot difficult RF problems in our fully-equipped lab in East London.

Antenna design, matching networks,
and RF fault-finding.

R/01

Antenna design & tuning

We design and characterise microwave antennas, including PCB patch arrays. We model them in Sonnet Electromagnetics, prototype, then measure, adjust and tune them in-system to produce a reliable and repeatable design.

R/02

Matching networks & frontends

We design matching networks and complex RF frontends, including mixed-signal PCB assemblies. We have experience with a wide range of RF components and technologies, including GaN, GaAs, SiGe and CMOS.

R/03

Filters & amplifiers

We design RF filters and amplifiers from DC to mmWave. Our in-house RF envelope is below 6 GHz and 20 W, with projects outside of this range supported by our network of associate specialists.

R/04

RF troubleshooting

We systematically diagnose and fix difficult RF problems – instability, interference, EMC, spurious emissions and poor range or sensitivity. Our agile approach means we iterate quickly, at your site or in our lab in Bethnal Green, London.

Connectivity where coverage runs out

DXComm manufactures and supplies advanced satellite communications equipment to defence, maritime and emergency-response operators who need reliable connectivity in places L-band constellations can't usually reach – such as operations bunkers, hangars, mines, tunnels and oil rigs.

These challenging RF environments require a flexible and agile engineering approach, and we're proud to support DXComm with bespoke RF components, services and consulting enable them to rapidly respond to the needs of their diverse clients.

How an engagement runs

Agile, flexible, iterative design.

Every engagement follows a documented sequence, aligned with the Agile methodology. Our process adapts to your roadmap and method of work, supporting your ISO 9001 / AS9100 workflows if required.

01 · Scope

Define the problem

Starting with a free 30-minute consultation, we'll write a scope covering the assumptions and your goals. The project will be broken down into phases, with a fixed estimate cost for each. Each phase is about 3-4 weeks of work.

02 · Design

Design iteratively

At the beginning of each phase, we carefully review and agree the scope. We'll then start the technical work, designing the product schematic, RF, PCB and firmware in industry-standard tools such as KiCad and Sonnet.

03 · Prove

Measure, don't assume

We meet with you every week, or on a cadence you determine, until the phase is complete. This ensures our work is closely aligned with your requirements.

04 · Hand over

Documented handover

You receive a handover at the end of each phase, ready for the next phase on your timeline. Design-and-source escrow can also be arranged through an independent UK escrow agent, so continuity is assured.
