5.2 Gain and P1dB

Recommendations and comments:

  1. Take into account losses of coax and attenuators to and from the EVM board
  2. Take into account losses of traces on the board up to the I/O pins of the DUT
  3. Power meters are typically a few tenths of dB more accurate than a signal generator's level controls and spectrum analyzer measurement capability. For precise measurements, use a power meter to measure the output of the signal generator and output of the TRF37x73/75 EVM.
