*Components not normally populated.
NOTES:
C11 selected to Fine Tune L4 for IF Output Match at 280 MHz.
R2 is normally not populated. For applications requiring additional LNA IP3, see the datasheet for recommended resistance values.
C1a and C2a are normally not populated. If C1a and C2a are populated, the LNA and mixer can be tested independently.
In this case, C1 and C2 should be removed.
To use the part with onboard filter, do not populate C1a, and C2a.
Use C1 and C2 instead. This will allow cascaded operation only.
