Features:
Single-Hardware Multi-Band Coverage – One unified PA module supports five FDD bands (B1/B3/B5/B7/B8) from 800MHz to 2.6GHz, simplifying inventory management and accelerating multi-frequency field deployments.
Optimized GaN Energy Efficiency – Leverages advanced Gallium Nitride (GaN) technology to operate at just 3.5A (48V), drastically cutting heat generation and power supply costs compared to traditional LDMOS modules, especially in high-density 50W deployments.
Superior Signal Fidelity & Consistency – Ensures exceptionally clean transmission with ≤5% EVM (at 10.0dB PAR), while maintaining a low ≤2dB in-band ripple across both UL and DL paths to guarantee stable modulation quality across the entire operating spectrum.
Balanced High-Gain Architecture – Features 53±2dB downlink gain and 25±2dB uplink gain with a low ≤3dB noise figure, delivering powerful output while preserving sensitive receiver performance.
Comprehensive RS485 Remote Supervision – Full-duplex 19200 baud telemetry allows real-time remote adjustment of gain and ATT values, plus instant queries on forward power (accuracy ±1dB) and temperature (accuracy ±3℃) via standard module-testing software.
Intelligent Self-Protection Mechanism – Automatic dual-threshold defense: immediate active fault reporting triggers an alarm if forward power exceeds the limit by +2dB; hardware-based thermal shutdown at 85°C with auto-recovery at 65°C ensures failsafe operation.
Flexible Downlink Conditioning – Integrated digital ATT provides a gain adjustment range of ≥25dB, coupled with an ALC range of ≥10dB to stabilize output power against input signal fluctuations, with flatness controlled within ±1.5dB.
Space-Saving Compact Footprint – Ultra-slim 150×100×23mm mechanical design allows seamless retrofitting into space-constrained RRU housings or pole-mounted enclosures without compromising thermal performance.
Versatile Multi-Interface Connectivity – Hybrid connector configuration (MCX for PA IN, SMA for LNA IN/PA OUT/LNA OUT) provides flexible RF routing options, simplifying PCB layout and cable harness assembly during system integration.
Rapid Out-of-the-Box Deployment – Ships with PC-based testing software to quickly validate critical parameters (gain flatness, alarm thresholds, and forward power detection) during factory acceptance or on-site commissioning.
