01
Antenna integration
Trace, chip and PIFA antennas tuned to your board’s actual groundplane, with keep-outs, matching network and EM-simulated radiation before fab.
Connected devices that ship at volume.
An IoT product lives or dies by three things: range, battery life, and BOM cost. We design PCBs that integrate the radio, hit the budget, and pass FCC/CE the first time — without paying the pre-cert module tax forever.

The deliverables.
02
Ultra-low-power PDN
Coin-cell or Li-ion PDN sized for sleep plus burst, with leak paths hunted: every nA budgeted, not hoped for.
03
Pre-cert layout
FCC Part 15 / CE RED (EN 300 328 and friends) layout discipline — emissions controlled at the IC, not the chamber. We’ll tell you when a pre-cert module path is cheaper.
04
Volume-cost optimization
DFM tuned to your CM’s real cost drivers — panel utilization, placement count, and assembly stations — not a generic checklist.
Built for this sector.
Standards we design to
- FCC Part 15 (intentional radiators)
- CE RED + EN 300 328 / EN 301 893
- EN 62368-1 (safety where applicable)
- Bluetooth SIG layout guidelines
- Wi-Fi Alliance / Thread integration notes
Radios + links
- BLE 5.x + Mesh
- Wi-Fi 4 / 5 / 6 (2.4 / 5 GHz)
- Thread / Zigbee / Matter
- LoRa / sub-GHz ISM
- Cellular Cat-M1 / NB-IoT modules
Power + form factor
- Coin-cell, LiPo, USB-C charging
- Energy-harvesting front-ends
- Tight rigid-flex form factors
- Module-or-discrete tradeoff analysis
- OTA-friendly memory layout
An asset tracker hitting 6-month battery on a CR2032.
The brief
A BLE 5 asset tag had to do hourly pings, weekly Wi-Fi geo-fencing scans, and last 6 months on a 235 mAh coin cell. Pre-cert had to pass on the first sample.
What we did
- Re-floorplanned the antenna keep-out and re-tuned the matching network against the actual ground geometry, not the eval board’s.
- Hunted the sleep-current path: switched the boost converter, gated the I²C pull-ups, and clamped a leaking GPIO — total Iq dropped from ~9 µA to ~0.7 µA.
- Pre-cert review against EN 300 328; passed conducted emissions with a single ferrite bead instead of the planned LC.
Outcome
Measured ~6.4 months on a 235 mAh CR2032 at the customer’s duty cycle; CE pre-cert passed on the A-sample with no layout re-spin.
Common questions.
Should I use a pre-cert module or a discrete radio?
Below ~10k/yr, a pre-cert module almost always wins on certification cost. Above that, a discrete radio plus chip antenna pays back in BOM. We’ll show you the break-even on your volume, not push either choice.
Will the antenna ‘just work’ on my board?
Almost never. Chip antennas need a ground-plane shape, a matching network and a keep-out the datasheet rarely shows. We tune against your actual board, not a reference design.
Do you handle the FCC / CE filings themselves?
We design to pass and run pre-compliance reviews. Filing and chamber testing go through a partner test house; we hand off a known-passing layout and the pre-cert log.
Ship the IoT, not the next re-spin.
