6. TEST METHODS
(1) Mixer input section
(a) With 50
resistance termination
(b) With 50
LC matching
Note
Since the values of L and C are affected by the board’s parasitic capacitance and inductance, L and
C should be adjusted so that the impedance looking at the MIX IN pin side from the signal source is
50
.
