Uziwave TDD 28V Multi Band Series POWER Amplifier

Features:
TDD mid-power booster design – Delivers 25W (44±1dBm) downlink output at 28V with ≤2.5A operating current, balancing coverage and power efficiency.

Independent CMOS TDD switching – Separate 3.3V logic controls for RX/LNA (uplink) and TX/PA (downlink), enabling precise synchronization with TDD frame timing.

Wideband TDD band support – Available for B34 (2.0GHz), B39 (1.9GHz), and B40 (2.3GHz) with in-band ripple ≤2.5dB (B40) or ≤2dB (others).

Real-time monitoring with 19200 baud RS485 – Queries module status, forward power (±1dB accuracy), temperature (±3°C), and triggers alarms for over-power (+2dB) or over-temperature (85°C shutdown / 65°C resume).

Integrated ATT & ALC control – Downlink gain adjustment ≥25dB and ALC range ≥10dB, with active fault reporting for power, VSWR, and temperature anomalies.
