    Acts as an "attenuator" instead amplifier and inserts about 10dB of noise, I´m very disapointed with this product. See the pictures, the first one is with the board, and the secont, wtihout this board

    It works. I cannot say the gain is 40db, maybe is 30-35 db. The noise level is not so low but at this price is a good general purpose width bandwidth amplifier.

    Received item in 3 weeks in spite of logistic delays due coronavirus. Quality is good. Has pair of SBB5089Z. Have not tested yet. Will use for QO-100 Satellite uplink.

    Качественный усилитель, если нет больших требований к линейности. Хочу заказать еще несколько штук. Прошу связаться со мной продавца.

    Provato a 470 MHz e a 800 MHz alimentato a 5 V stabilizzati con uA7805 funziona. Difficile per la strumentazione in mio possesso misurare il guadagno.
