MRF486

The MRF486 is designed for application as a high-power linear amplifier from 1.5 to 30MHz. The features of MRF486 include: (1)low-cost, common-emitter TD-220AB oackage; (2)specified 28V, 30MHz performance: output power=40W, power gain=15dB min, efficiency=40% min; (3)intermodulation distortion @ 40W: IMD=-30dB max.

The following is about the absolute maximum ratings of MRF486: (1)collector emitter voltage: 35V; (2)collector-base voltage: 65V; (3)emitter-base voltage: 4.0V; (4)collector current-continuous: 3.0A; (5)withstand current: 6.0A; (6)total device dissipation @ TC=25: 87.5W; (7)storage temperature range: -65 to 150.

The electrical characteristics of the MRF486 are: (1)collector-emitter breakdown voltage: 35V at IC=50mA, IB=0; (2)collector-emitter breakdown voltage: 65V at IC=50mA, VBE=0; (3)collector-base breakdown voltage: 65V at IC=5.0mA, IE=0; (4)collector cutoff current: 10mA max at VCE=28V, VBE=0, TC=25; (5)DC current gain: 10 min and 40 typ at IC=2.0V, IE=0, f=1.0MHz.
