Blueline ECO750 – Most modern components and a highly efficient layout design result in lower thermal power loss. This power amplifier works according to the Doherty principle with an up to 20 % higher efficiency factor.
This amplifier uses especially efficient LDMOS semiconductors from European manufacturers, providing both energy efficiency and high amplification. Because of the compact but robust design the amplifier is suited for mobile and stationary applications as well. For mobile use or during contest operation the high efficiency layout will be especially useful of course. But also at home you will benefit from it.
