This parameter is especially important to determine the maximum linear RF input power for an RFoF solution. A signal that is stronger than the P1db point of the RFoF system, it will be compressed and distorted. This causes the RFoF system not to be able to produce the same RF signal at the far end.
RFOptic provides an option to its customers to adjust the P1dB compression point to fit their needs, In the GUI configurable units, P1dB point can be adjusted by modifying the S21 gain levels. In higher frequency units (8 Ghz – 20 Ghz), RFOptic can still adjust the parameter by incorporating a pre- and/or post LNA (low noise amplifier) based on the customer needs.
