2.3 Input Connectors

There are six output connectors (SMA) on the EVM.

  • LNA INPUT (J10): Connects to LNA input of the device. This has 50 ohm termination and is AC coupled to the device LNA input and also has a back to back diode for device input protection from overvoltage.
  • LOG INP+ (J1): Connects to the non inverting input (Log i/p +) of the log detector block through a capacitor (AC coupled). This also is 50 ohm terminated and has a double stacked back to back diode to protect the device input pin from overvoltage.
  • LOG INP- (J6) : Connects to inverting input of the LOG detector (Log i/p -). This can be used when feeding differential signal to LOG detector. The input structure is same as that of LOG INP+. To enable this connection R29 need to be connected.
