(1) An external matching network is required (see section “Recommended assembly plan”)
(2) The IF optimum load for conversion loss is 200Ω. For minimum noise figure this load can
be lower, the best results have been obtained on 50Ω.
(3) Measured on 200Ω IF impedance.
(4) An external resistor controls the bias current (see section “Typical bias and IF
Configuration”)
