7. Redo GIC Components
:
After obtaining the optimumnetwork between the SAW and
Mxer RF input, most likely Idd will have changed slightly.
Determne a new GIC resistor to bring Idd to the desired
value.
8. Double Check IF Match
After any change which affects IF stage current it is important
to recheck the IF output match. This is especially true when
matching down to 50ohms, since the match is more sensitive.
A match to a 1000ohmfilter will not be as sensitive. The LO
must be turned ON during the test.
9. Test the TQ5635 Cascade:
Finally after the LNA and Mxer are properly tuned the device
performance as a whole should be measured.
