Microwave Dielectric Ceramic Duplexer Product Introduction:
The microwave dielectric ceramic duplexer is a passive RF device that utilizes high-Q, low-loss microwave dielectric ceramics as the core resonant medium, integrating both transmit and receive filtering channels. It enables the sharing of a single antenna for both transmission and reception, providing simultaneous signal isolation at the same frequency without interference. It features a small size, stable performance, and high integration, making it a core component in RF front-end systems.
Microwave dielectric ceramic duplexers are widely used in: IoT terminals, industrial communications, base station equipment, automotive electronics, portable communication devices, and satellite navigation and communication.
