The amplifier has the advantages of wide frequency range, high gain, small noise coefficient and so on. It can be used in various RF receiver front-end and increase communication distance. Wide range shortwave, FM broadcasting, remote control receiver, CATV signal amplifier

Working frequency: 0.1-2000MHz

Amplifier gain: as shown in the following figure

F= 0.1MHz, gain=32dB

F= 500Mhz gain=31dB

F=1000MHz gain=29dB

F=1500Mhz gain=25dB

F=2000MHz gain=20dB

Maximum output power: +10dBm (10mW) @1dB compression point

Working current: 35mA (9V)

Power supply voltage: 6--12VDC

System impedance: 50 ohm

1) when the operating frequency is less than 500MHz, the amplifier has a very good gain flatness and can be carefully adjusted to less than 1dB. The higher the frequency, the higher the gain consistency.

2) the lower operating frequency of the amplifier is controlled by the input and output capacitors, the default is 0.1uF, and it can work to 0.1MHz. The input and output capacitors can be appropriately increased to extend the lower frequency limit, such as 10uF, and it can work to 5KHz. For detailed calculation, it is necessary to pay attention to the input and output impedance of 50 Europe, to calculate the capacitance of the capacitance, and to enhance the decoupling and voltage regulation of the power supply.

3) when the power supply voltage changes in 5-8V, it can be used as a variable gain amplifier, and the gain increases with the increase of the power supply voltage. It is very suitable for radio frequency receiver front-end circuit. The power supply voltage is controlled by DA, thus the gain of the amplifier is controlled and automatic gain control is used.

4) when the power supply is at 8-10V, the gain of the low frequency end reaches 30dB, and the amplifier has a lower noise coefficient and better stability.
