Notes:
1. C11 is selected to fine tune L4 for IF output match at 210 MHz.
2. R3 is not normally populated. For applications requiring additional LNA IP3, see the datasheet for
3. C2 and C3 are not normally populated. If C2 and C3 are populated, the LNA and mixer can be tested
recommended resistance values.
independently; in this case, C1 and C5 should be removed.
