Microsemi Introduces Two New RF MOSFET Transistor Products Operating At 175MHz And 100MHz

June 25, 2009

Irvine, CA (GlobeNewswire via COMTEX News Network) -- Microsemi Corporation (Nasdaq:MSCC) a leading manufacturer of high performance analog mixed signal integrated circuits and high reliability semiconductors, has introduced two new RF MOSFET power transistor products capable of operating at up to 175MHz and 100MHz for their targeted applications.

The new VRF152 is a gold-metalized silicon n-channel RF power transistor designed for broadband commercial and hi-rel applications requiring high power and gain without compromising reliability, ruggedness or inter-modulations distortion. It can operate up to 175MHz at 150W with a typical gain of 13dB at very high efficiency on a 50V DC supply.

Key Performance Features of the VRF152
* High 130V breakdown voltage for improved ruggedness
* Low 200mohm Rdson for improved efficiency
* Typical 22dBgain at 30MHz
* Typical 13dB gain at 175MHz
* 30:1 VSWR
* Nitride passivated and gold metallization for improved reliability

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.

The 500 piece pricing for the VRF152 is $53.14 and $45.48 for the ARF477FL. Contact the factory or local sales contacts for other quantity pricing and delivery.

Both new Microsemi RF MOSFET products are available for immediate sampling and have technical information available on the Microsemi website, http://www.microsemi.com. Samples can be ordered through this site, or from Microsemi sales representatives and authorized distributors.
