Special Instructions (Board loss, taking into consideration description in the schematic)
LNA
VCC1 =VCC2=Enable=2.75V; Mix Gain =0.0V
To measure ICC LNA only:
LNA Gain was switched between 0V and 2.75V, and record the delta current.
Mixer
VCC1=VCC2=Enable=Mix Gain=2.75V; LNA Gain=0.0 V
To measure ICC Mixer (LNA should be in bypass mode and LO signal should be present):
Total mixer current=ICC1
VCC2 only affects LO current buffer and R6 doesn’t affect the mixer current.
