Interface Schematic

1, 3, 7, 10, 12

GND

Package bottom has exposed metal paddle that must also be

connected to PCB RF ground.

2, 11

RF1

RF2

This pin is DC coupled and matched to 50 Ohm. Blocking

capacitors are required if the RF line potential is not equal to

0V.

4, 9, 13, 14, 15, 16

N/C

This pin should be connected to PCB RF ground.

5, 8

V2, V1

Control input (master).

6

I

Control input (slave).

External op-amp control circuit maintains impedance match while attenuation is varied. Input control ranges from 0 Volts

(min. attenuation) to -3.0 Volts (max. attenuation.)
