Features: brand new and high quality The amplifier has very good gain flatness when the operating frequency is less than 500MHz. The lower the frequency, the higher the gain consistency. The lower limit of the operating frequency of the amplifier is limited by the input and output capacitors, which are 0.1uF by default and can work up to 0.1MHz; the input and output capacitors can be appropriately increased to extend the lower limit of the frequency. Attention should be paid to the decoupling and voltage regulation of the power supply during application. When the supply voltage varies between 5-8V, it can be used as a variable gain amplifier, and the gain increases with the increase of the supply voltage. Using DA to control the supply voltage, you can control the gain of the amplifier and adjust the gain. When the supply voltage is 8-10V, the gain at the low frequency end is 60dB, and the amplifier has a lower noise figure and better stability. When the voltage is 12V, the gain is large, and the gain at the low frequency end can reach 62dB. Due to the amplifier gain (60dB), the input should be overloaded (Fmax=-50dBm), and the relevant principles of RF microwave circuit layout should be followed in use.
