Products
Communication radiator (indoor)
Indoor cooling base cools 5G indoor high-frequency components and provides a protective assembly frame
• High heat dissipation requirement-large tonnage die casting
• Local high-efficiency cooling solution–embedded heat pipe technology
• Overall high-efficiency heat-dissipating solution–dispensing wings
Intelligent combiner cavity
Intelligent combiner is a kind of filter, which combines two signals into one signal, which is used for AP, CDMA & GSM & DCS & PHS & 3G and other WLAN dual-frequency combiners.
• small volume
• Band stop filter, freely switchable frequency band
• Hole depth 200mm, hole accuracy ± 0.02mm
• High plating requirements, stable filtering function
• Frequency band: DC-690 ~ 862 MHZ / 880 ~ 960 MHZ
Communication radiator (outdoor)
When high-frequency signals and microwaves are fed into the circuit, heat will inevitably be generated. As the frequency of 5G equipment increases, more heat is bound to be generated. The 5G filtering heat dissipation cavity is to deal with this heat dissipation problem.
• Tooth height 120mm, larger profile size
• Welded 4 profiles using FSW technology to save costs
• 100% airtight test pass
Communication radiator (outdoor)
When high-frequency signals and microwaves are fed into the circuit, heat will inevitably be generated. The fin inserting process and the application of highly thermally conductive materials will significantly improve the heat dissipation problem of the cavity.
• Material: High thermal conductivity aluminum
• Use wing insert technology to meet the high tooth requirements that die casting cannot achieve
• The pulling force of each fin can reach an average of 2KN
• Copper is installed in the cavity to improve local heat dissipation performance
