DRF1400 [Microchip]

DRF hybrid RF power amplifier products enable superior power density by integrating RF MOSFETs with gate drivers in a single package with excellent thermal performance. Integration maximizes amplifier performance by minimizing transmission line parasitics between the driver and the MOSFET.

Products are offered with the following configurations.

• DRF1200, DRF1201, DRF1211: single-ended topology for simplest design
• DRF1300, DRF1301, DRF1311: push-pull topology for easy design with outstanding 2^nd harmonic suppression
• DRF1400: half-bridge topology for higher efficiency and power density
• DRF1510: full-bridge topology for most compact, most efficient Class-D RF amplifier in a single package

Reference designs are available as a learning tool and development platform to enable minimal time-to-market, including detailed application note, circuit schematics, bill of materials, circuit board layout, theory of operation, and performance data.
