Features:
1. Designed for high-demand 4G infrastructure
Engineered to deliver 80W dual-channel output with exceptional linearity and thermal efficiency, supporting continuous operation in base station and repeater applications.
2. Dual-directional gain control with ALC integration
Features independent uplink and downlink gain paths, with downlink ALC range ≥10dB and gain adjustment ≥25dB for precise signal conditioning under varying input conditions.
3. Real-time system health monitoring and logging
Built-in telemetry for forward power, temperature, VSWR, and fault status, accessible via RS485 (9600 baud) for integration into remote supervision platforms.
4. Fail-safe over-power and over-temperature protection
Automatically triggers alarms and disables the amplifier when output exceeds +2dB above max rating or temperature reaches +85°C, with automatic recovery at +65°C.
5. High-isolation Tx-Rx path design
Achieves ≥55dB isolation between transmitter and receiver paths, minimizing leakage and improving system sensitivity in full-duplex FDD operation.
6. Low-noise uplink performance
Uplink noise figure ≤3dB ensures weak signal integrity, ideal for cell-edge scenarios and environments with high interference or long cable runs.
7. Wide operating temperature range for outdoor deployment
Fully functional from -40°C to +55°C, with derating and thermal management designed for solar-powered or remote telecom shelters.
8. Modular RS485 command set for integration flexibility
Supports gain setting, status query, and alarm retrieval through a simple software protocol, enabling custom control logic without additional hardware layers.
9. Compact mechanical layout with dual-wire 28V power input
Mechanical dimensions optimized for 19" chassis or pole-mount enclosures, with dual-wire 28V DC input reducing wiring complexity in field deployments.
10. Seamless frequency band customization
Available in B1 (2.1G), B3 (1.8G), B7 (2.6G), and B8 (900M) variants, allowing operators to standardize on a single hardware platform across multiple 4G bands.
