  • SMB RF connector transmit power
    SMB RF connector transmit power Jun 07, 2022
        The importance of the transmit power of the SMB RF connector is that the transmitter's signal needs to be spatially faded before it can reach the receiver, so the higher the transmit power means the farther the communication distance. So, do we want to pay attention to SNR? For example, if our transmit signal has a poor SNR, is the signal SNR arriving at the receiver also poor?  ...
  • What is the RF connector PIM value?
    What is the RF connector PIM value? May 29, 2022
        Regarding the main performance PIM value (passive intermodulation) in the RF connector, you may only know that there is this performance value, but what is the use of it, and what effect it will have on the performance of the RF connector. How much loss is there in the signal transmission of the device.      The PIM value (Passive Intermodulation) is a distorted s...
