Reference design kit enables RF engineers to evaluate Class-D amplifier

Irvine, Calif.—Microsemi Corp. has announced a 1.7-KW, 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 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 include greater than 1700W 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; and solid state transition for tube amplifiers.

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 in 100-piece quantities.

All devices are available through the factory or from authorized distributors of Microsemi RF products.
