Technology & Quality

Ashwing filters are developed on a proven RF design platform, with core filter technology developed in cooperation with Beijing Chipment Technology — a national high-tech enterprise specializing in RF measurement instruments and antenna design.

Simulation-Driven Design

Full-wave EM simulation and coupling-matrix synthesis ensure first-pass accuracy and consistent roll-off characteristics across production lots.

100% VNA Testing

Every unit is swept on a vector network analyzer (S11/S21/S22) before shipment; test plots available with each delivery on request.

Sealed for the Outdoors

IP67-rated housing with stainless hardware and −40 to +85 °C rating, qualified for tower-top and airborne environments.

Volume Production

The full series is in mass production with stable lead times. Custom pass bands, connector options (N-type) and tuning available on request.
