Microsemi Announces New 1.7KW RF Generator Reference Design Kit
Prime Newswire
May 06, 2008: 08:30 AM EST
IRVINE, Calif., May 6, 2008 (PRIME NEWSWIRE) -- Microsemi Corporation (Nasdaq:MSCC), a leading manufacturer of high performance analog/mixed signal integrated circuits and high reliability semiconductors, has announced a 1.7KW, Push Pull, Class-D reference design kit that enables RF design engineers to immediately evaluate a highly efficient, high power, Class-D amplifier.
Based on Microsemi's DRF1300 Driver/MOSFET hybrid, the new reference design kit provides an essential tool in developing high-power, high-voltage RF generators, optimizing efficiency and power densities for plasma generation, switch mode power amplifiers, pulse generators, ultrasound transducer drivers and acoustical optical modulators.
KEY FEATURES
* Greater than 1700 Watts Output Power
* Better than 80% Efficient Class-D Operation
* 13.56 MHz Switching Frequency
* Up to 250 Supply Voltages
* Internal MOSFET Rated at 500V BV(DSS)
* Low Cost System Design
* Solid State Transition for Tube Amplifiers
Class-D amplifiers offer a degree of efficiency unavailable with linear designs. Many engineers, however, avoid the complexities of Class-D amplifier designs -- or are forced to spend months acquiring its fundamentals. Now, with Microsemi's new DRF1300/Class-D reference design kit, engineers can rapidly overcome the pitfalls of high voltage Class-D design, saving months of designer time and countless design iterations.
Using Microsemi's DRF1300 Driver/MOSFET hybrid as its core, the kit's reference board enables performance levels previously unachievable with solid state Class-D amplifiers. The DRF1300 hybrid combines two drivers, two high voltage MOSFETs and internal bypass capacitors in a push pull configuration making it a highly efficient, high voltage, cost effective solution. The drivers combined with optimally located bypass capacitors are capable of driving the high voltage MOSFETs at more than 30MHz. The 500V MOSFET enables high voltage applications, greatly simplifying output matching and reducing complexity of the output combining networks.
The new Microsemi Class-D reference design kit includes a designer's application note discussing the progression through various output voltages, while identifying proper output waveforms necessary for safe transition to greater than 1700 watts into a 50 Ohm load. It also demonstrates how to achieve efficiencies higher than 90% at sub 1KW outputs. It demonstrates supply bypassing and building the high power magnetics required for high power Class-D designs. The board comes fully assembled and is mounted to a machined heatsink.
The Class-D reference design kit is extremely versatile. After evaluating a design with the preloaded 500V, 30A DRF1300 hybrid, applications can be modified for higher voltage requirements by using the 1000V, 15A DRF1301 Driver/MOSFET hybrid.
The DRF1300 hybrid features an air cavity-flangeless package for improved reliability over plastic encapsulated packaging. Constructed with materials with closely matched CTEs the flangeless package maximizes system reliability by alleviating the stress between components during power cycling. Typical applications have demonstrated in excess of 1 million cycles with power densities of 700 Watts/square inch. The flangeless package design also reduces cost, eliminating expensive copper tungsten flanges that are typical in conventional high power RF packages.
DRF1300/Class-D reference design kits are available now, with a unit price of $1600. Samples of the DRF1300 and DRF1301 Driver/MOSFET hybrids are also available now. Additional DRF1300 hybrids are available for a unit price of $225.00 in 100 piece quantities. All devices are available through the factory or from authorized distributors of Microsemi RF products.

Microsemi Adds Lowest-Light Sensor to Its Patented Visible Light Sensor Portfolio
Wednesday April 16, 8:30 am ET
IRVINE, Calif., April 16, 2008 (PRIME NEWSWIRE) -- Microsemi Corporation (NasdaqGS:MSCC - News), a leading manufacturer of high performance analog mixed signal integrated circuits and high reliability semiconductors, has announced a new lowest-light addition to its patented visible light sensor portfolio.
Designated the LX1973B(tm), the new sensor features an innovative dome-lens package and dark-current cancellation technology optimized for lowest light levels, making it an ideal solution for automatic brightness control in automotive displays, auto-dimming mirrors and headlamps, as well as for targeted applications in computer notebooks, LCD monitors and TVs, handheld displays, cell phones, digital cameras, kiosks and outdoor lighting.
``We designed the LX1973B to provide the most accurate and controlled response even under very low ambient light conditions,'' said Steve Litchfield, Microsemi Executive Vice President and Analog Mixed Signal Group President. ``The LX1973B utilizes what we call Best Eye(tm) processing which provides a nearly perfect photopic light wavelength response curve.''
The sensor provides a current output with a 10% accuracy maintained over the full temperature range making it ideal for those applications where a frequency output would interfere with other electronics and where the tightest control is required.
When interfaced with an 8-bit ADC, the LX1973B can detect light as low as 0.001 lux and as high as 500 lux. An integrated dark current cancellation circuit enables accurate sensing at less than 0.0005 lux @ 25 degrees Celsius. In addition, internal thermal compensation provides high accuracy over an extended temperature range, from -40 to +85 degrees Celsius.
Unlike conventional light sensors, Microsemi's patented technology requires no optical filters for ultraviolet and infrared wavelengths that extend beyond human sight. These wavelengths can confuse conventional sensors, which must use infrared filters to avoid display lighting adjustments erroneous to the human eye.
The LX1973B is lead free and contains no cadmium, as is found in many conventional light sensors.
The LX1973B is available in an 8-pin MSOP surface mount package measuring only 3 millimeters square. Package orientations are offered for both standard board mounting (package suffix IPL) and for reverse mounting (package suffix IPR). If needed, two sensors can be mounted on opposite sides of the board -- an ideal solution for applications such as auto-dimming mirrors.
In 2.5K quantities the LX1973B sensor is unit priced at $2.46. Samples and production quantities are available immediately.
Complete technical information on all Microsemi visible light sensors is available on the Microsemi web site at http://www.microsemi.com. Samples and evaluation boards can be requested through this site, from Microsemi sales representatives, or from Microsemi's distribution channel.
