Challenges: · Subway environment has limited space, with a multi-band (380-400MHz) shared antenna feed system, requiring high-isolation combiners to prevent intermodulation interference between different channels. · Circulators with load protection are required at the output ends of base stations and repeaters to protect the power amplifier modules from power reflection and interference damage. · Devices are required to have anti-

A certain military industrial unit is developing a new generation of tactical communication equipment, which needs to cover ultra-wideband transceiver front-ends and requires devices to have high power handling capability, low noise, and anti-interference characteristics. Challenges: · Traditional discrete devices are large in size and have high insertion loss, which cannot meet the miniaturization requirements of handheld/vehicle-mounted platforms. · Military environments need to meet G

With the large-scale deployment of 5G base stations, the transceiver channels inside the base stations are dense, highlighting issues of signal crosstalk and reflection, which puts extremely high demands on the performance and reliability of RF circulators and isolators. Challenge: Base station AAUs (Active Antenna Units) need to integrate multi-channel transceivers within a limited space, requiring circulators/iso
