We are using the ADF4360-9 in an application that only uses the DIVOUT signal and does not make use of the RF output pins A&B. Can these pins be left unconnected? If not, what are the minimum components required on the RF outputs to insure proper operation on the DIVOUT pin? The space we have on our board is very tight and it would be very desireable if we did not need to use the output matching components on the RF output pins. Currently we are using the output matching circuit shown in figure 33 of the data sheet. We have experimented with disconnecting the output matching circuit from the RF output pins and did not notice any difference in operation at the DIVOUT pin. Are these components really necessary?
