Features:

High-Power Output: Delivers 53 ± 1 dBm (≈200W) output power over the dedicated 2400–2500 MHz band.
ALC & Wide Gain Adjustment: ≥10 dB ALC control range plus ≥25 dB gain adjustment range with excellent step accuracy (≤±1.5 dB max error).
RS485 Remote Monitoring & Control: Real-time queries for module status, over-power alarm, over-temperature alarm, amplifier temperature, ATT value, and forward power (accuracy <±1 dB).
Robust Protection with Continuous Operation: Over-temperature shutdown at +100°C, restart at +80°C; VSWR alarm does not disable the amplifier – normal output continues.
Compact Mechanical Design: Small footprint of 150 × 100 × 24 mm with SMA input and rugged N-type output connector, operating at 28V / ≤17A.

Single-tone signal testing; 28V dual-wire power supply for the amplifier.
Amplifier features RS485 communication functionality.
1. VSWR alarm: Amplifier continues normal operation after VSWR alarm is triggered.
Connectors: SMA input, N-type output.
