The typical gain is 35 dB, the low frequency gain is higher, and high frequency gain may be little declined. The amplifier is used for all kinds of RF signal low noise amplification, can increase the reception effect. Connect this amplifier to receiving antenna output, it can magnify the receiving weak signals, thus expand receiving distance. Widely used for low noise RF signal amplification such as in short wave, FM radio, walkie-talkie, GPS and Beidou receiver, wifi and so on.
