Features:
GaN-Based 50W TDD Amplifier for 3.4GHz Band – Delivers 47±1dBm downlink output across 3200–3400MHz with 53±2dB gain, purpose-built for ad-hoc network deployments requiring high-power density in mid-band spectrum.
Ultra-Low Latency for Tactical Communications – Achieves ≤2μs signal transmission delay, meeting stringent timing requirements for real-time ad-hoc, mesh, and tactical radio applications.
Uplink with Integrated Interference Rejection – Embedded uplink filtering suppresses out-of-band interference and reduces spectral congestion, improving signal quality in dense RF environments.
High Efficiency with GaN Technology – Powered by 48V with only 4A current draw, delivering 50W output with exceptional power-added efficiency and minimal heat dissipation.
Hardware-Only Thermal Protection – Fixed-threshold over-temperature shutdown at +85°C with automatic restart at 65°C, ensuring failsafe operation without software or external controller dependency.
No Monitoring – Simplified Architecture – Deliberately omits RS485 monitoring to reduce system complexity, eliminate potential failure points, and lower unit cost for high-volume ad-hoc deployments.
Robust Environmental Tolerance – Operates reliably from -40°C to +55°C ambient, supporting deployment in extreme outdoor and field conditions without performance degradation.
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, eliminating external RF switching components.
Compact GaN-Optimized Chassis – Housed in 170×110×22mm enclosure with MCX (PA IN/LNA OUT) and SMA (ANT) connectors, enabling easy integration into portable transceivers and compact radio nodes.
Clean RF Performance for Ad-Hoc Applications – Maintains ≤5% EVM at 8dB PAPR and ≤2.5dB in-band ripple, ensuring reliable modulation quality for OFDM and QAM waveforms in challenging field environments.
