Description
Power supply for RF LNA.
External RF bypass capacitors are required.
Power supply for second stage of LO amplifier.
External RF bypass capacitors are required.
Power supply for first stage of LO amplifier.
External RF bypass capacitors are required.
This pad is AC coupled
and matched to 50 Ohms.
This pad is DC coupled for applications not requiring
operation to DC. This port should be DC blocked exter-
nally using a series capacitor whose value has been
chosen to pass the necessary frequency range. For
operation to DC, this pad must not source / sink more
than 3 mA of current or die non - function and possible
die failure will result.
This pad is AC coupled
and matched to 50 Ohms.
The backside of the die must be
connected to RF/DC ground.
