Applications Across Industries

Telecomm

Antennas, filters, and couplers for cellular, satellite, and broadband systems.

Aerospace & Defense

High-precision waveguide components, shielding, and resonators for radar and communication systems.

Medical Devices

RF shielding and antennas for imaging or diagnostic equipment.

Automotive

Components for signal processing in ADAS.

Antenna Components

  • Patch Antenna Elements
    Flat, metallic patches precisely etched to specific geometries for creating directional or omnidirectional antennas.
  • Reflectors & Radome Parts
    Thin metallic reflectors to direct RF signals, often paired with antenna arrays to improve gain and beam direction.
  • Beamforming Elements
    Metal arrays or grids designed to shape and steer RF beams for applications like phased arrays or MIMO systems.

Filters

  • Combline Filter Plates
    Intricate metal plates with parallel resonator structures that filter specific frequency bands, commonly used in RF signal processing.
  • Cavity Filter Components
    Often called resonators, pin connectors, etc.
  • Filter Housing Covers & Perimeter Lids

Couples & Dividers

  • Directional Coupler Grids
    Thin metal grids that split or combine RF signals, ensuring minimal loss and directional signal flow.
  • Power Divider Plates
    Components designed to evenly distribute power from one source to multiple output ports, often used in antenna arrays.
  • Hybrid Coupler Housings
    Metal parts used in RF circuits to combine or split signals with specific phase relationships (e.g., 90° or 180°).

Waveguide Components

  • Waveguide Irises
    Thin metal inserts placed inside waveguides to control impedance, improve matching, or filter signals.
  • Aperture Plates
    Precisely etched plates that guide RF signals through transitions, often used in mode conversion or filtering.
  • Waveguide Flange Covers
    Thin metal covers for protecting waveguides, with optional etched holes for ventilation or signal coupling.

EMI/RFI Shielding

  • Shielding Enclosures & Covers
    Metal boxes or covers designed to enclose RF circuits, preventing interference from external signals.
  • Perforated Shields
    Shields with etched holes or patterns allowing controlled signal transparency while maintaining EMI/RFI protection.
  • Low Profile Shields
    Shields with minimum, formed wall heights of .050”

Resonators

  • Microstrip Resonators
    Freestanding metal components used to create high-Q resonant circuits, often in radar or telecommunication systems.
  • Dielectric Resonator Housings
    Etched metal structures that house dielectric materials, enhancing their electromagnetic properties.

Thermal Management

  • Thin Metal Heat Spreaders / Heat Sinks
    Flat, etched plates of copper or aluminum designed to distribute heat from RF components evenly.
  • Micro-channel cooling plates
  • Heat Exchanger plates

Mounting & Support Structures

  • Bonding Frames
    Precision-cut metal frames for holding or aligning RF components, ensuring accurate placement in assemblies.
  • Precision Brackets
    Small metal brackets used to secure RF circuits or antennas, often requiring complex shapes.
  • Lead Frames

Gaskets & Frames

  • EMI/RFI Gasket Frames
    Thin metal frames designed to provide a conductive seal between surfaces, preventing RF leakage.
  • Precision-Cut Metal Seals
    Custom-shaped seals that ensure electrical continuity and environmental protection in RF systems.

Tuning & Adjustment Elements

  • Tuning Stubs & Slots
    Small metal elements that can be adjusted or trimmed to fine-tune RF circuits, enhancing performance.
  • Adjustable Mounting Plates
    Metal plates with slots or adjustment features to position or align components during assembly.
  • Shims & Spacers

Our process is exceedingly precise, and our team is knowledgeable about industry regulations. We will work with you to ensure your component allows your finished product to comply with standards. The first step is a finished component that meets the exact specifications of your design. Our process is unmatched in precision.

Features

  • Tolerances as low as 10% of material thickness
  • Metal thickness range from .001”- .125″
  • Outside corner radius are equal to 20% material thickness
  • Controlled depth etch features (Bend lines, part identifiers, etc) typically up to 50% thickness within +/- .001”
  • Etching is a burr-free and stress-free process. Stamping and machining impart thermal and mechanical stresses to parts, and the function of some parts require that these stresses are not present. Etched parts are also flatter for this reason.
