Hardware Design
End-to-end hardware design for RF, power, control, sensing, and embedded electronic systems— from schematics and PCB layout to bring-up, protection logic, and test fixtures. Focused on RF power paths, precision sensing, and controller-friendly interfaces.
What We Design
RF & Power Boards
- HF–6 m RF paths, couplers, and sampling networks
- LDMOS amplifier support boards (bias, rail switching, protection)
- Directional couplers, load interfaces, and sensing front-ends
Control & I/O Boards
- Controller companion boards (Teensy / ESP32 / MCU)
- Relay drivers, PTT interlocks, LPF/ANT switching
- Current, voltage, and temperature sensing (ADC-friendly)
Measurement & Protection
- Hardware interrupts for SWR, over-drive, over-current, over-temp
- Frequency-sense paths (square-wave outputs for band detection)
- Fuse selection, TVS, snubbers, and layout for safe operation
Integration & Retrofits
- Drop-in boards for existing amplifiers or station controllers
- Adapter cards, harness pinouts, mating to existing backplanes
- Designs that expose clean headers for third-party MCUs
Custom Electronic Modules
Beyond RF and power hardware, we design a wide range of embedded and system-level modules for industrial, hobbyist, and commercial applications. Whether you need a drop-in module, a controller add-on, or a complete product motherboard, we can take it from concept to production-ready.
Sensor & Measurement Modules
- Temperature, current, voltage, pressure, environmental sensors
- High-resolution ADC front-ends (ADS1115, INA series, etc.)
- Digital/analog hybrids, filtering, and signal conditioning
Control & Automation Modules
- Relay / MOSFET driver boards
- GPIO expansion, I/O muxing, shift registers
- Stepper/servo/BLDC interface layers
MCU Companion Boards
- Teensy / ESP32 / RP2040 modules and shields
- Display, keypad, encoder, and user-interface backplanes
- Power conditioning, regulators, and isolated interfaces
Capabilities
Schematic & Layout
- KiCad-based schematic capture and multi-layer PCBs
- Controlled-impedance RF traces and power planes
- Connector, relay, and high-current path optimization
Power & Protection
- High-side switching (smart switches, MOSFET arrays)
- Current sense (shunt + ADC / dedicated ICs)
- TVS, fusing, and fault-handling strategies
RF-Aware Details
- Coupler design (tandem match, sample level targeting)
- Grounding, returns, and layout around relays & contacts
- Test headers and hooks for NanoVNA / VNA verification
Toolchain & Deliverables
Toolchain
- KiCad projects (schematic, PCB, 3D viewer-ready)
- Mechanical outlines suitable for enclosures and heatsinks
- Optional 3D exports for mechanical integration
Deliverables
- Source design files (KiCad), PDFs of schematics
- Gerbers, drill files, assembly drawings, BOMs
- Bring-up notes, test points, and basic procedures
Engagement Models
New Designs
Clean-sheet boards based on your requirements and constraints.
Revisions & Upgrades
Iterating on existing boards to add features or improve robustness.
Consult & Review
Design reviews, layout feedback, and second-opinion checks.
Process
- Discovery: use-cases, voltage/current ranges, RF bands, safety needs
- Concept: block diagrams, connector strategy, protection strategy
- Design: schematic capture, PCB layout, BOM selection
- Fabrication & Bring-Up: prototype boards, bench tests, tweaks
- Handoff: final files, notes, and options for firmware / software tie-in
