4O3A Power Genius XL 3X1 HF/6M Amplifiers

4O3A Power Genius XL 3X1 HF/6M Amplifiers are solid-state amplifiers capable of delivering 1500W+ output across the 160-6M amateur bands, engineered for high-performance amateur radio use. The PGXL 3X1 uses dual NXP MRF1K50H LDMOS transistors, each rated for 1.5 kW, providing high headroom, low IMD, and clean signal output.

The Power Genius XL 3x1 features a 3-to-1 antenna switching module, allowing you to connect three antennas to a single radio. As a result, the software interface differs slightly to accommodate this functionality. The integrated MEffA™ algorithm dynamically adjusts DC voltage for optimal efficiency. Additional features include fast SWR protection, advanced thermal management, and seamless integration with FlexRadio systems via SmartSDR. They also support third-party radios through Ethernet, RS232, CI-V, and BCD interfaces.

NOTE - These Amplifiers are shipped without a power connector on the end of the power cable. Customers are urged to work with their electrician to finalize AC power delivery.
