Features:
Dual-band ad-hoc network coverage – Supports two precise band options (2.8–3.0GHz and 3.0–3.2GHz), tailored for flexible deployment in mesh and ad-hoc communication systems.
High-gain 20W TDD output – Delivers 43±1dBm downlink power with 53±2dB gain and ≤5% EVM at 8dB PAPR (10MHz bandwidth), ensuring robust signal integrity.
48V GaN efficient power stage – Achieves high energy conversion efficiency with ≤2.5A operating current, plus over-temperature (85°C shutdown / 65°C resume) and over-power protection.
RS485 full telemetry interface – Provides 19200 baud communication for real-time queries of forward power (±1dB accuracy), temperature (±3°C), alarm status, and remote gain/switching control.
Compact chassis with CMOS frame control – Housed in 140×110×22mm enclosure with MCX (PA IN) and SMA (LNA OUT / ANT) connectors, plus separate 3.3V logic inputs for TX/PA and RX/LNA TDD switching.
