Features:

Ultra-Broadband Operation Covers 20–700 MHz in a single module, eliminating the need for band-switching.
High Linear Output Power Delivers ≥49 dBm (≈80 W) at 28 V and ≥49.5 dBm (≈89 W) at 32 V, suitable for high-power transmission systems.
GaN Technology with High Efficiency Gallium nitride (GaN) design ensures high power density, low current draw (≤10 A @ 28 V, ≤9 A @ 32 V), and improved thermal performance.
Wide Gain Adjustment Range Provides ≥25 dB of attenuation control with precise 1‑dB step linearity, enabling flexible system integration.
Comprehensive RS485 Monitoring & Control Supports remote settings (on/off, gain) and real-time queries (status, temperature, output power) via standard RS485 interface.
Smart Thermal Management Built-in over-temperature protection with programmable threshold (+100 °C alarm/shutdown, +80 °C auto-recovery) ensures reliable operation in harsh environments.
Wide Operating Temperature Range Qualified for –40 °C to +55 °C, suitable for outdoor, industrial, and defense applications.
External Enable Control TTL-compatible EN pin with high-level disable (1.8–5 V) and low-level enable (0–0.5 V); floating defaults to normally ON for fail-safe operation.
Compact Mechanical Footprint Space-saving dimensions of 222 × 110 × 26 mm, facilitating integration into rack-mount or portable systems.
Standard RF Interfaces SMA input and N-type output connectors for easy cabling and system compatibility

Test Signal: CW signal during test.
Supply Voltage: 28–32 V DC, GaN technology, dual-wire feed.
External EN Enable:
- High level (DC +1.8 V to +5 V) → Disable
- Low level (DC 0 V to +0.5 V) → Enable
- Floating (open) → Default Normally ON.
Output Protection: No internal isolator; open-circuit at output is prohibited.
Output Connector: N-type female.
