As demand for high‑reliability non‑reciprocal components accelerates across 5G/6G, defense radar, satellite links, and MRI systems, OEMs and system integrators increasingly seek ODM partners who can co‑design, validate, and scale manufacturing with predictable performance. Hzbeat provides end‑to‑end ODM manufacturing services for RF circulators and isolators from 20 MHz to 200 GHz, balancing low insertion loss, high isolation, and stable VSWR for mission‑critical deployments.

• EM Design & Simulation: Full‑wave EM using industry tools (e.g., HFSS/CST equivalents), parametric sweeps, and tolerance analysis; TRL/LRM de‑embedding for fixture removal.
• Materials & Magnetics: Ferrite selection and bias network design; optional LTCC/ceramic integration for compact stacks.
• Power & Thermal: CW/pulsed handling, load‑pull‑informed matching; thermal paths modelled for conduction and forced convection environments.
• Precision Machining & Assembly: Tight‑tolerance housings, controlled pressure contacts, surface finishes for low PIM.
• Test Infrastructure: VNAs up to 200 GHz (as required), time‑domain gating, PIM checks, power burn‑in; automated test scripts for lot‑level uniformity.
• Documentation & Traceability: Traveler records, serialized labeling, and COA per lot; change control with ECN/PCN workflow.

• Microstrip / SMT: Compact, low profile for radios and TR modules.
• Drop‑in: Robust junctions for moderate/high power, easy integration.
• Coaxial: Wide bandwidth, convenient lab/field replacement.
• Waveguide: High power and low loss at Ku/Ka and above.

Standard and custom options cover VHF/UHF through mmWave up to 200 GHz with tailored matching networks to meet IL, Isolation, Return Loss, and Phase/Amplitude stability targets.

• Processes: ISO 9001‑aligned QMS; controlled suppliers; incoming inspection.
• Environmental Tests: Thermal cycling/soak, vibration (per common methods akin to MIL‑STD‑202), humidity, salt fog where applicable.
• Screening: Burn‑in, 100% S‑parameter sweeps, power handling checks, and lot AQL sampling.
• Compliance: Support for aerospace/medical documentation as required by the application.

• Defense & Aerospace: AESA T/R isolation at X/Ku/Ka; data links for ISR and TT&C.
• 5G/6G Infrastructure: Base‑station radios and fixed wireless; small‑cell backhaul.
• Satellite Communications: Gateways and user terminals across Ku/Ka; LEO/GEO payload support.
• Medical Imaging (MRI): High‑power transmit isolation and LNA protection.

Q1: What is ODM in RF?

ODM (Original Design Manufacturer) means Hzbeat not only manufactures under a client’s brand but also contributes design, simulation, and co‑development to meet target specs across 20 MHz–200 GHz.

Q2: How do you ensure performance matches the model?

We correlate EM simulation with de‑embedded VNA results (TRL/LRM), use golden‑unit references, and maintain process windows with SPC on critical dimensions.

Q3: Can you support rapid iterations?

Yes—fast loops from EM model → CNC/PCB → bench test, with automated report packs (S‑parameters, IL/ISO/VSWR, thermal notes).

Q4: Engagement process?

Share specs via Contact Hzbeat; we sign NDA if needed, propose architecture and plan, then execute proto → pilot → MP with agreed KPIs.

• IEEE MTT‑S resources on non‑reciprocal devices and ferrite components.
• Industry practices for TRL/LRM de‑embedding and VNA calibration up to mmWave.
• Community standards and methods aligned with ISO 9001 and typical MIL‑STD‑202 environmental tests.
