ARF477FL -- RF Power MOSFET Transistors

The new ARF477FL is a 500V (BVdss) push-pull matched pair transistor product providing up to100MHz operation in the ISM Band for industrial, scientific and medical applications including semiconductor capital equipment and MRI systems.

It is capable of delivering 400W CW power up to 80 MHz. In pulse applications it will produce 1500W peak power at 5ms@ 25 per cent duty cycle. Typical gain at 65 MHz is 17dB in class AB at 300W output operating from a 125V supply.

The ARF477FL is housed in Microsemi's exclusive T3 "flangeless" package that delivers superior thermal performance at considerable savings over conventional RF packaging. The T3 package utilizes Microsemi's patent-pending lid for improved thermal contact to heat sinks.
