Features:

High-Frequency Wideband Coverage: Operates from 2500 MHz to 6000 MHz, delivering ≥47 dBm (50W) output power from a single-stage GaN design.
Precise Step Attenuation: ≥25 dB gain adjustment range with excellent 1 dB step linearity at 10 dB, 20 dB, and 25 dB attenuation settings.
RS485 Remote Monitoring & Control: Enables real-time queries for module status, over-temperature alarm, amplifier temperature, and forward output power, plus remote on/off and gain control.
Comprehensive Protection Features: Over-temperature alarm/shutdown at +85°C with auto-recovery at +65°C (software configurable); output must not be left open-circuit (no isolator).
Compact & Low Power: Ultra-compact 222 × 85 × 25 mm housing with dual SMA connectors, drawing ≤5A at 32V, and supporting –40°C to +55°C operation.

CW Signal Testing
Wideband power detection accuracy: ±3 dBm
32V, GaN, dual-wire power supply
External EN (Enable) control:
1. High level (DC +1.8V to +5V): Disable (amplifier off)
2. Low level (DC 0V to +0.5V): Enable (amplifier on)
3. Floating (no connection): Default on
No isolator – output must not be left open-circuit
