Instructions (Board loss, taking into consideration description in the W-CDMA schematic)
LNA
ICC LNA current=total current (VCC=LNA Gain=2.75)-total current (VCC=2.75; LNA Gain=0)
To measure ICC LNA only:
LNA Gain was switched between 0V and 2.75V, and record the delta current.
Mixer
ICC Mix and bias current=total current (VCC;=EN =VCC2=Mix Gain=2.75; LNA Gain=0)-total current (VCC;=EN=2.75;
Mix Gain=LNA Gain=VCC2=0
LO signal should be present. VCC2 only affects LO current buffer and R6 doesn’t affect the mixer current.
