TYPICAL PERFORMANCE CHARACTERISTICS

INSERTION LOSS, RETURN LOSS, AND ISOLATION

Insertion loss and return loss measured on the probe matrix board using ground signal ground (GSG) probes close to the RFx pins;

isolation measured on the evaluation board because signal coupling between the probes limits the isolation performance of the ADRF5044

on the probe matrix board.
