Pin Number

Function

Description

Interface Schematic

1, 2

N/C

This pin may be connected to the housing

ground or left unconnected.

3Vdd

Power supply for the LO Amplifier. An external RF bypass capacitor

of 100 - 330 pF is required as close to the package as possible.

4RF

This pin is AC coupled an matched to

50 Ohm from 20 - 30 GHz.

5IF

This pin is DC coupled and should be DC blocked externally using

a series capacitor whose value has been chosen to pass the neces-

sary IF frequency range. Any applied DC voltage to this pin will

result in die non-function and possible die failure.

6LO

This pin is AC coupled and matched to

50 Ohm from 10 - 15 GHz.

7

GND

Must be soldered to PCB RF ground.
