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