Function

Description

Interface Schematic

1Vdd

Power supply for the LO Amplifier. An external RF bypass

capacitor of 100 - 330 pF is required. A MIM border capacitor

is recommended. The bond length to the capacitor should be

as short as possible. The ground side of the capacitor should

be connected to the housing ground.

2RF

This pad is AC coupled

and matched to 50 Ohm.

3IF

This pad is DC coupled and should be DC blocked

externally using a series capacitor whose value has been

chosen to pass the necessary IF frequency range. Any applied

DC voltage to this pin will result in die non-function and pos-

sible die failure.

4LO

This pad is AC coupled

and matched to 50 Ohm.
