APPENDIX D: TYPICAL RETURN-LOSS
Figure D-1 shows the return-loss at the BNC
connector of the EQCO62R20.3 evaluation board as
shown in Section 2.0 “Application Information” with
supply current of 0 mA and 703 mA (maximum supply
current for CoaXPress) through the inductor (L1) and
the ferrite beads (Fb1 & Fb2) and compares it with the
CoaXPress (Full-Speed) return-loss specification.
