Description

1 x LNA 50-4000MHz SPF5189 RF Amplifier. This RF low noise amplifier LNA is 50-4000MHz, NF = 0.6dB. LNA: 50-4000mhz. In the case of amplifying weak signal, the noise of the amplifier itself may be very serious, so it is hoped that this noise will be reduced to improve the signal-to-noise ratio of the output.
