Uziwave GRQ-20-700M-100W GaN Broadband Amplifier

Features:
1. Ultra-Broadband Operation
Covers 20–700 MHz in a single module, eliminating the need for band-switching.
2. 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.
3. 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.
4. Wide Gain Adjustment Range
Provides ≥25 dB of attenuation control with precise 1‑dB step linearity, enabling flexible system integration.
5. Comprehensive RS485 Monitoring & Control
Supports remote settings (on/off, gain) and real-time queries (status, temperature, output power) via standard RS485 interface.
6. 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.
7. Wide Operating Temperature Range
Qualified for –40 °C to +55 °C, suitable for outdoor, industrial, and defense applications.
8. 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.
9. Compact Mechanical Footprint
Space-saving dimensions of 222 × 110 × 26 mm, facilitating integration into rack-mount or portable systems.
10. Standard RF Interfaces
SMA input and N-type output connectors for easy cabling and system compatibility
