7. TEST CIRCUIT EXAMPLES

In test circuit example 2 onward, only the portion that differs from test circuit example 1 is shown.

Test Circuit Example 1.

Caution

The 10 pF capacitor value for IF2 OUT and RSSI OUT includes all the capacitances (board,

pattern, etc.) applied to the pin. Ensure that the recommended load condition (10 pF) is not

exceeded for IF2 OUT and RSSI OUT.

Remark

Chip laminated ceramic capacitors (MURATA GRM36 or equivalent) should be used.
