Operating at a frequency range of between 423- to 443-MHz, the BLP05H9S500P LDMOS transistor can deliver up to 500-W output power in pulsed or continuous wave modes and enables so far untapped drain efficiency levels of typically 75%. Such best in class 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 50-V 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.
