18GHz WAVEGUIDE DUPLEXER
Enables full‑duplex communication with minimal system complexity
Available in circulator‑based and filter‑based architectures
Stable performance over temperature and vibration
Application Scenarios / Working Scenarios of a WAVEGUIDE DUPLEXER
Pulse radar systems –
A WAVEGUIDE DUPLEXER allows the radar to transmit a high‑power pulse through the antenna and then switch to receive mode to listen for echoes, sharing the same antenna.
Continuous‑wave (CW) radar and FMCW radar –
A WAVEGUIDE DUPLEXER enables simultaneous transmit and receive operation for Doppler and frequency‑modulated radar.
Satellite communication (Satcom) ground stations –
A WAVEGUIDE DUPLEXER separates the uplink (Tx) and downlink (Rx) signals that share a common dish antenna.
Electronic warfare (EW) systems –A WAVEGUIDE DUPLEXER protects the receiver from the jamming transmitter's high power while allowing both to share one antenna.
Aerospace and avionics (weather radar, collision avoidance) –
A WAVEGUIDE DUPLEXER is a critical component in airborne radar systems that use a single radome‑mounted antenna.
