The VBA400-80 is a member of our family of 10kHz400MHz high power amplifiers, designed primarily for EMC applications.
Like all our products of the VBA400 series, it is based on rugged push-pull MOSFET technology, for extra even order harmonic suppression.
The amplifier operates in class A, the benefits for EMC applications being very low distortion and tolerance of 100% mismatch. Fold-back protection is neither fitted nor needed! This makes it supremely suited for very demanding transducer requirements.
