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
Excellent quality fast delivery.The packaging is very reliable

THANKS
ok
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.
Works like it should.
