Microsemi Corp. 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 and 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 1,700W output power; better than 80-percent efficient Class-D operation; 13.56MHz 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 with a unit price of $1,600. Samples of the DRF1300 and DRF1301 Driver/MOSFET hybrids are also available. Additional DRF1300 hybrids have a unit price of $225 in 100-piece quantities.
