Amplificador de 6W para módulos PLL FM, usando transistores C1970 e C1971 - Versão final 04-04-2022

Imagem
Este amplificador para módulo PLL pode fornecer uma potência de até 6w. Este transmissor tem alcance de até 15km em linha visada, cobre tranquilamente um bairro quando usado uma antena de boa qualidade, instalada em um ponto alto da cidade. Link para construção da antena dipolo para o transmissor de FM  Clique aqui . Montagem e calibração do amplificador: Os transistores C1970 e C1971 podem ser soldados em pé e compartilhar o mesmo dissipador de calor. Monte o amplificador por etapas fazendo ajuste da potencia e das ondas estacionárias (ROE). A primeira etapa de pré- amplificação é compreendida até o capacitor variável CV4. Conecte o wattímetro ao CV4 e ao terra, conecte o wattimetro à antena dipolo, calibre a potencia e o ROE. A potencia nesta etapa ficará entre 60mw e 120mw dependendo do ganho do transistor BD135. Os BD135 da NPX tem um ótimo ganho. Monte a etapa de média potencia compreendida até o CV6 e repita a calibração da potencia e do ROE. Nesta etapa a potencia deve ser de
