Uziwave 4G-FDD-80W-DUAL Power Amplifier

Features:
Engineered for continuous high-load operation – Maintains RF consistency and stability across full -40℃ to +55℃ ambient range, with autonomous thermal protection activating at +85℃ and resuming at +65℃.

Embedded diagnostics with active anomaly reporting – Continuously tracks power output, load mismatch (VSWR), internal temperature, and system faults, proactively notifying host systems via RS485 interface.

Dual-domain signal conditioning – Features independent ATT (≥25dB range) and ALC (≥10dB range) control on downlink, enabling precise output regulation and automatic over-power safeguarding.

Low-profile, high-density mechanical architecture – Optimized for space-constrained enclosures, combining dual-channel 80W capability with a 28V dual-wire power input and efficient current draw (≤9A with APD).

Modular frequency‑selective variants – Available across four FDD bands (B1/B3/B7/B8) within a unified 80W platform, simplifying integration for multi-band 4G base station and repeater systems.
