What made you select the Ampleon ART500PE1 as a featured product?
I chose the Ampleon ART500PE1 because it offers up to 500 W RF output power from an LDMOS transistor in a cost-effective TO247 package and provides an attractive alternative to the NXP MRF300, giving close to 300 W output when operated at 50 V. Based on Ampleon’s Advanced Rugged Technology (ART), the device operates from 1 to 250 MHz and is designed for high-power ISM, broadcast and non-cellular communications applications. With drain efficiency reaching 81% at 27 MHz, it is particularly interesting for designers looking to reduce power dissipation and simplify thermal management.
Thermal performance and ruggedness are important considerations in high-power RF designs. Applications such as industrial heating, plasma generators and MRI systems often require continuous operation at high power levels. The ART500PE1 offers high breakdown voltage, excellent thermal stability and ruggedness under its specified operating conditions. Higher efficiency also means less power is dissipated as heat, which can reduce the demands on the cooling system.
Another useful feature is the flexibility in operating voltage. The ART500PE1 is characterised from 30 to 65 V and qualified for operation up to 65 V. Its high breakdown voltage also supports Class E operation up to 53 V. Integrated dual-sided ESD protection allows Class C operation and complete transistor switch-off. Mirrored pin-out versions are available, making it easier to use two devices in a push-pull configuration. The standard TO247 package also simplifies assembly and provides a cost-effective option for engineers developing new designs or evaluating alternatives to existing LDMOS devices.
