Specification: Item Type: RF Broadband Material: Aluminum Alloy Color: Silver + Gold Working Frequency: 2K-3000MHz Gain: 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) at 1dB Compression Point Noise Figure: 1.9dB Power Supply Voltage: 9-12VDC System Impedance: 50Ω Purpose: Frequency Broadband Package List: 1 x RF Broadband Note: Do not use it outside the range of voltage current or frequency. How to use: 1) The amplifier has very good gain flatness when the operating frequency is less than 500MHz and careful adjustment can be less than 1dB. The lower the frequency the higher the gain consistency. 2) The 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. 3) When 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. 4) When 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. 5) When the voltage is 12V the gain reaches the maximum valu
