PLT12-102S

 

General information

The PLT12-102S power amplifier operates at frequency of 162,50MHz and it is rated for continuous duty at an RF output power of 1000 Watts. It is mainly designed as final power stage and it uses a single last generation LDMOS device capable of 1000 W RF output. The module is realized with a very compact layout to maximize the number of pallet in high power amplifiers and include the bias circuits, matching network and circuits for stabilization of the operating point. The configuration of the amplifier is a “push-pull” stage coupled by means of the combining network fully integrated in the RF block. This design allows obtaining broadband high efficiency and extremely low harmonic emissions.
