IF1IN
The mixer output is an open collector of a bipolar transistor. The minimum voltage at
these pins is 5 V (VS - voltage swing). The DC current into these pins is typically 9 mA.
Good LO and RF suppression at the mixer output can be achieved by symmetrical load
conditions at the pins MIXOUT1 and MIXOUT2.

ESD
The typical input resistance is 330 â¦. The DC voltage is almost identical to the reference
voltage. DC current must be avoided at this pin.
