*C om ponents not norm ally populated.
NOTES:
C11 selected to fine tune L4 for IF output match at 210 MHz.
R2 is norm ally not populated. For applications requiring additional LN A IP3, see the data sheet for
recom m ended resistance values.
C1a and C 2a are norm ally not populated. If C 1a and C2a are populated, the LNA and m ixer can be
tested independently. In this case, C 1 and C 2 should be rem oved.
To use the part w ith onboard filter, do not populate C 1a, and C 2a.
Use C1 and C2 instead. This w ill allow cascaded operation only.
