NOTES
1The balance in the bias current in the two legs of the mixer input may be important in applications were a low feedthrough of the LO is critical.
2This voltage is proportional to absolute temperature (PTAT). Reference section on DC-Coupling the LO for more information regarding this interface.
3Response time until device meets all specified conditions.
