The RF cable assemblies factory talks about the knowledge of RF cable assemblies, mainly introduces the receiving dynamic range of RF cable assemblies.
The dynamic range of the receiver of the RF cable assemblies is actually related to the two indicators mentioned before, the first is the reference sensitivity, and the second is the receiver IIP3.
The RF cable assemblies factory believes that the reference sensitivity actually represents the minimum signal strength that the receiver can recognize, and will not be repeated here. Mainly talk about the maximum reception level of the receiver. The maximum receive level is the maximum signal that the receiver can receive without distortion. This distortion can occur at any stage of the receiver, from the pre-LNA to the receiver ADC.
The RF cable assemblies factory simply has a negative feedback loop: detect the received signal strength (too low/high) - adjust the amplifier gain (up/down) - the amplifier output signal ensures that it falls on the input dynamics of the next stage device within the range. This is a simplified design with the idea that the goal of the receiver RF chain is to keep the desired signal input to the receiver ADC within the dynamic range and to keep the SNR above the demodulation threshold.
