Description
30K-200M Broadband Programmable Amplifier 0 to 65dB Adjustable Gain Amplifier Module Gain Control Step 0.5dB
Product Description
The input signal of the module needs to be greater than 10mV when the frequency is lower than 1MHz, and the lowest 2mV signal can be amplified when the frequency is higher than 1MHz. The default configuration of the module has a maximum gain of 65dB, which can be measured when the frequency is 50MHz and the input is 2mV. At this time, the output is about 4100mV.
Note
(1) The power supply of the module is a positive and negative dual power supply, and the voltage cannot exceed 5.5V. (2) Since the module is a high-precision device, in order to avoid unnecessary interference, it is recommended to use a linear power supply. (3) For the output signal, it is recommended to use the SMA to BNC line to input and output signals. Use an oscilloscope to observe the effect. Poor contact or poor quality wires may cause signal attenuation or excessive noise.
