Features:
Sub-1GHz Long-Range TDD Amplifier – Operates across 260–360MHz with superior propagation characteristics, delivering 40±1dBm (10W) output for extended-range ad-hoc and tactical communication networks.
Exceptional Propagation for Non-Line-of-Sight – Leverages VHF/UHF low-band frequencies to penetrate foliage, buildings, and terrain obstacles, significantly outperforming higher-frequency solutions in rural and urban canyon environments.
Uplink with Integrated Interference Rejection – Embedded filtering on the receive path suppresses out-of-band interference, improving receiver selectivity in congested spectral environments.
Balanced Gain Architecture for Low-Band – Provides 45±2dB downlink gain and 10±2dB uplink gain with ≤3dB noise figure, optimized for long cable runs and distributed antenna systems.
Hardware-Only Thermal Protection – Fixed-threshold over-temperature shutdown at +85°C with automatic restart at 65°C, ensuring fail-safe operation without software or external controller dependency.
No Monitoring – Maximum Simplicity – Deliberately omits RS485 monitoring to reduce system complexity, eliminate potential failure points, and minimize unit cost for high-volume ad-hoc deployments.
Fixed-Gain Architecture for Predictable Performance – No gain adjustment or ALC circuitry, ensuring consistent, predictable RF performance without risk of misconfiguration in field deployments.
Wide Environmental Tolerance – Operates reliably from -40°C to +55°C ambient, supporting deployment in extreme outdoor and field conditions without performance degradation.
Ultra-Compact Low-Power Chassis – Housed in industry-leading 110×70×18mm enclosure with ≤3.2A current draw at 28V, ideal for man-portable radios, UAV payloads, and space-constrained nodes.
CMOS 3.3V TDD Frame Synchronization – Independent logic inputs for TX/PA and RX/LNA switching (high=enable, low=disable) provide precise alignment with TDD slot timing; MCX (PA IN/LNA OUT) and SMA (ANT) connectors simplify integration.
