RF Next Design is an independent RF design practice: low noise amplifiers, power amplifiers, RF switches and mixed-signal PCBs, plus hands-on design consultation.
The best RF products are won in the schematic and the stack-up.
Matching, stability, noise and linearity are worked out in simulation before any board is built.
Grounding, stack-up, isolation and thermal paths decide whether the simulation survives on the PCB.
VNA, spectrum analyzer and noise measurements confirm the circuit meets its target.
Five core services, from a single amplifier stage to a complete mixed-signal board.
MMIC and discrete pHEMT LNAs tuned for noise figure, gain and stability.
10–25 W GaN amplifier stages with attention to linearity, efficiency and heat.
Switch networks for transmit and receive paths, with a focus on isolation and insertion loss.
RF, analog, digital and power on one board without them interfering.
Independent advice on architecture, parts and risks, from first idea to prototype review.
Circuit and EM simulation, then VNA and spectrum validation on the bench.
Measured and simulated targets from amplifier and front-end work.
Custom discrete LNA with matched noise and gain, fabricated and tested.
High gain and stability across the band, with impedance and noise optimisation.
High-power stages for wideband radio transmit chains.
Circuit and EM design from DC to 10 GHz.
Real RF board designs with their schematics and key specifications.
Every stage of an RF design, from the first schematic to thermal checks.
Drag up on a module to open it and see what is inside. Drag down to close it.
Amplifier moduleEnclosure, PCB, heatsink and two SMA connectors.
RF switch moduleEnclosure, PCB, RF shield and three SMA ports: antenna, TX and RX.
Radio links over a few kilometres or 36,000 km follow the same maths. We plan them before hardware is built.
Link budgets for GEO and other orbits, including path loss, antenna gain and margin.
Terrestrial links planned for range, throughput and reliability.
Channel selection and interference mitigation before deployment.
Terrain-aware coverage estimates and optimisation.
Bring a specification or a half-working prototype. We work through it in the same order every time.
Two browser tools built by RF Next Design. Open them straight from here.
From free-space path loss to reliability, charted live as you type. Includes a radio log analyser.
Sample readout, Ku-band downlink
