Design and application of a frequency band multi-system cavity combined with 5G
A 1-in-2-out POI system is designed aiming at the coexistence of 4G and 5G networks.It realizes signal combination transmission between WLAN and 4/5G multi-system.The system is characterized by small interpolation loss of the combined circuit,high port isolation,large power capacity,and high temperature stability.It is capable of avoiding mutual interference between systems.In addition,the POI enjoys advantages such as small size,high performance,low cost,easy mass production,etc.
