In modern communication networks, five band signal boosters are becoming the core equipment for solving multi standard compatibility issues. CB70B series five band signal booster, as 4G signal amplifier, breaks through industry bottlenecks through three major innovations.
1、 RF architecture revolution
(1) Five bands independent channel design
700/800/850/900/1700/1800/1900/2100/2600MHz ect independent circuit, ensuring the isolation of the five band signal booster is greater than 30dB.
(2) Penetration enhancement mechanism
70dB gain with beamforming allows the five band signal booster to penetrate 3-layer concrete (-75dBm signal strength).
The cast aluminum ice-metal chassis dissipates heat from high-power amplification, preventing thermal throttling in metal workshops.
4G signal amplifier's adaptive algorithms avoid self-oscillation, a key feature for industrial base station interference elimination.
(3) Thermal Management Revolution
Triple cooling architecture of cast aluminum ice metal chassis:
① Aluminum substrate thermal conductivity 201W/(m · K)
② Phase change material buffers 45 ℃ thermal shock
③ Infrared coating cooling
This thermal design synergizes with ALC automatic protection – at 55℃ ambient, the system dynamically reduces gain by 3dB to prevent shutdown.
Validated in automotive plants: 4G signal amplifier sustained full power for 2,000hrs at 55℃ inside cast aluminum ice-metal chassis.
2、 Intelligent protection system
(1) ALC automatic protection system establishes a triple line of defense:
Millisecond level response: The system establishes a triple line of defense with millisecond-level response.
Core ALC Action: The ALC automatic protection cuts off output for 0.1 seconds when VSWR >15dB is detected.
This safeguard is critical for the integrated Five band signal booster, ensuring reliable operation across all supported frequencies.
(2) Physical protection enhancement
The cast aluminum ice metal chassis has passed IP40 certification, increasing its anti-corrosion life by 6 times
Impact Resistance: 310MPa compressive strength protects the 4G signal amplifier from mechanical shocks.
The chassis design also optimizes heat dissipation for the 4G signal amplifier, maintaining stability during sustained operation.
(3) Energy saving and base station collaboration
Intelligent Sleep Logic:
Ultra-Low Power State: In unmanned conditions, power consumption drops to 3.8W (92% reduction).
Instant Recovery: Detects user entry and restores full power in 0.3 seconds.
Network Benefits: This enables base station interference elimination at night, significantly reducing network noise.
Combined with the ALC automatic protection, this synergy ensures zero interference to adjacent base station interference elimination during low-power states.
