Overview

The basic components of a multiplexer include various structural forms, such as bridge type (fixed impedance type), star type (star dot type), delay type (phase sensitive type), improved bridge type, and hybrid structure composed of various basic units, and digital TV multiplexers have achieved modular design. 
This quadcopter is a bridge structure, which has good scalability due to its broadband input port. Including filters, bridges, absorbing loads, and outer frame fixing brackets.

System Characteristics
1. Use purple copper, brass silver plated, and high-quality aluminum alloy materials as adjusting devices and cavity materials.
2. Low insertion loss and reflection, high standing wave ratio.
3. According to the frequency interval, a 6-cavity dual cross coupling filter is used.
4. High isolation design, using a full bridge structure.
5. Adopting frequency anti temperature drift design, and all regulating devices are equipped with locking fasteners to prevent changes in indicators during transportation and installation.
6. The overall frame is supported by flat steel for easy transportation and installation.
7. It is processed using advanced integrated molding technology, with no screw connections, seams, or welds between the filter cavities, ensuring that the product has extremely low insertion loss and excellent consistency.
