Desenvolvimento de Sistema de Recepção com Amplificação do Nível de Sinal Digital de Alta Definição

Abstract: Abstract-This paper presents the development of an a radiofrequency amplifier based on a transistor that operates at high frequency. In order of determining the increase of the signal level via amplification, a half-wave dipole antenna (λ / 2) with geometry inspired by the meander line antenna type (MLA) also is developed. Simulations using software based on the finite element method were performed and the antenna reception efficiency was evaluated through measurements.
