.Please tell me the impedance of LO input at 10MHz and also the value of the components(C3,C4,C5,L5) required for the reactive matching at this frequency
Thanks for the information.
For my application the signal output port(Pin 5&6) frequency range is from 1KHz to 20KHz, so according to Table7 & Figure 3 its working for 10MHz with L3=L4=0 i.e. no external component is required, only transformer is required for impedance matching.
So, "will this configuration work for 1KHz-20KHz (much lower frequency) output"
No information is available for such lower frequency IF output in the datasheet.
