①The amplifier has very good gain flatness when the frequency is less than 500MHz, and careful adjustment can be less than 1dB. The lower the frequency, the higher the gain consistency.
②The lower limit of the operating frequency of this amplifier is restricted by the input and output capacitors. The default is 0.1uF, which can work up to 0.1MHz; the input and output capacitors can be increased appropriately to extend the lower limit of the frequency. For example, at 10uF, it can work up to 5KHz. For detailed calculations, note that the input and output impedance is 50 ohms, calculate the required capacitance value, and at the same time enhance the decoupling and voltage regulation of the power supply.
③When the supply voltage changes between 5-8V, it can be used as a variable gain amplifier, and the gain increases with the increase of the supply voltage. It is very suitable for RF receiving front-end circuit. DA is used to control the power supply voltage to control the gain of the amplifier and play an automatic gain control.
④When the power supply voltage is 8-10V, the low-frequency end gain reaches 30dB. At this time, the amplifier has a lower noise figure and better stability.
⑤When the voltage is 12V, the gain reaches the maximum value, and the low-frequency end gain can reach 32.5dB.
