In the ADL5363 datasheet regarding the output interface is written: " DC Bias Voltage - Externally generated" and in the Footnote 1: "Apply the supply voltage from the external circuit through the choke inductors". (see Table 2, Page 3.) However, I cannot find any external DC bias components at the IF output in the Figure 47 "Typical Application Circuit" and in the Figure 48. Contrariwise, the DC coupling capacitors (C24, 25) prevent any external DC influence on the mixer operation.
My question is: Is it needed to apply some kind of DC bias to the mixer IF output? Thank You!
