MRF406

The RFG MRF406 is a high-power, NPN silicon RF power transistor engineered primarily for linear power amplifier applications in the high-frequency (HF) band. Operating at a standard 12.5-volt supply, it is housed in a specialized, gold-plated stripline package with dual mounting flanges designed for efficient heat dissipation and low-inductance connections. The component's markings indicate it belongs to date code lot 9551, and it is highly valued for building or repairing broadband RF power amplifiers, amateur radio equipment, and commercial transceivers due to its robust gain and power output characteristics
