TYPICAL PERFORMANCE CHARACTERICS

INSERTION LOSS, RETURN LOSS, AND ISOLATION

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

isolation measured on an evaluation board because signal coupling between the probes limits the isolation performance of the ADRF5021

on the probe matrix board (see the Applications Information section for details of evaluation and probe matrix boards).
