1. The amplifier is a 5-6000MHz (20dB) amplifier, which has the characteristics of large dynamic range and wide working frequency range, and is suitable for fixed gain amplification of radio frequency signals. 2. This amplifier has the advantages of wide frequency range, stable gain, small noise figure, large dynamic range (+20dBm@1dBP), etc. It is especially suitable for radio frequency transmitting circuits to increase the communication distance! 3. Widely used in shortwave, FM broadcasting, remote control receivers, cable TV signal amplifiers, Beidou, GPS satellite navigation, 2.4G Bluetooth, WIFI receiver RF terminals and other RF amplification places! 4. The amplifier has a shielded shell with anti-reverse protection diodes 5.
