500W LDMOS transistor saves space, cuts costs

The BLP05H9S500P LDMOS-based power amplifier transistor from Ampleon is designed for use in industrial heating, defrosting, plasma lighting and medical applications. Operating at a frequency range of between 423 to 443MHz, the device can deliver up to 500W output power in pulsed or continuous wave modes and enables so far untapped drain efficiency levels of typically 75%.

These characteristics will keep the required cooling capacity to a minimum while also saving both space and operation costs.

In addition, the lightweight push-pull transistor amplifier was specifically designed to withstand a VSWR of 10:1 at 50V through all phases with no damage or degradation, further simplifying the system design and protection circuitry.

The BLP05H9S500P is based on Ampleon’s 9th generation high voltage LDMOS process technology and comes in a low thermal resistance OMP780 package.

It is currently in production with a minimum longevity commitment of 15 years.
