01
RF stackup + material
Hybrid FR-4/Rogers builds that put the RF layer on a low-loss dielectric without paying for an all-Rogers board.
RF that meets the noise budget.
From 2.4 GHz Wi-Fi to 5G sub-6 and mmWave intros. Rogers/Megtron stackups, matched feeds, controlled-impedance transitions — EM-simulated and verified on the bench.

The deliverables.
02
Matched transmission lines
Microstrip, GCPW, and stripline feeds tuned to 50 Ω with via fencing and proper reference returns.
03
3D EM simulation
Connector launches, transitions, and antenna feeds checked in a full-wave solver before fab.
04
Isolation + shielding
Guard rings, stitching, cavity shields, and floor-planning that keeps the RX away from the switcher.

The brief
A 5.8 GHz RX/TX had to share a board with a Cortex-M, a buck converter, and DDR — and still hit its noise floor.
What we did
- Put the RF on a Rogers 4350B sub-stack; isolated it with a stitched guard ring and a shield can footprint.
- Routed the switcher return away from the LNA reference plane; added a localized quiet island.
- EM-simulated the connector launch and matched it to 50 Ω.
Outcome
Measured noise floor −110 dBm — within 2 dB of the standalone reference design, on a board a quarter the cost of a separate RF module.
Common questions.
Do I need an all-Rogers board?
Rarely. A hybrid build puts the RF layer on low-loss material and keeps the rest FR-4 — a fraction of the cost with almost all of the performance below ~10 GHz.
Can you design the antenna too?
We design PCB trace antennas (inverted-F, meander) and feed networks, and integrate chip antennas. For certified custom antennas above mmWave we partner with a specialist.
Do you handle FCC/CE pre-compliance?
Yes — layout for EMC and a pre-compliance review are part of our integrity services; full chamber testing is a partner referral.
