(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”)
