Pin Descriptions
Pin Number Function Description Interface Schematic
1, 3, 7, 9 GND
Package bottom has exposed metal paddle that must also be
connected to PCB RF ground.
2, 8
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, 6 V2, V1 Control input (master).
5 I Control input (slave).
10, 11, 12 N/C
This pin may be connected to PCB RF/DC ground.
Performance will not be affected.
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.)
Single-Line Control Driver

Evaluation PCB
The circuit board used in the application should
be generated with proper RF circuit design tech-
niques. Signal lines at the RF ports should be 50
Ohm impedance and the package ground leads
and package bottom should be connected directly
to the PCB RF ground plane, similar to that shown
above. The evaluation circuit board shown above is
available from Hittite Microwave Corporation upon
request.
