Notes:
1.
The R1 resistor can be modified for the CV221-2A to draw less current. Changing it from 13 to 18
Ω
is expected to have the converter draw 17mA
less current so that the converter will draw about 300mA typically under LO drive, while degrading the IIP3 performance by 0.5 dB.
The values shown above have the IF tuned at 240 MHz and will affect the optimal performance of the converter. For other frequencies, these
components need to be modified as follows:
