Pad Number Function Description Interface Schematic
1, 3, 10, 12 GND
Package bottom has an exposed metal paddle that
must also be connected to RF ground
2, 11 RFIN, RFOUT
This pin is DC coupled and matched to 50 Ohm. Blocking
capacitors are required if RF line potential is not equal to 0V.
4, 5, 6, 7, 8, 9 V6 - V1 See truth table and control voltage table.
13, 14, 16 N/C
This pin should be connected to PCB RF
ground to maximize performance

Pin Description
Suggested Driver Circuit
(One Circuit Required Per Bit Control Input)
Simple driver using inexpensive standard logic ICs provides fast
switching using minimum DC current.
* Recommended value to suppress unwanted RF signals at V1 -
V6 control lines.

Evaluation PCB
The circuit board used in the application should use
RF circuit design techniques. Signal lines should
have 50 Ohm impedance while the package ground
leads and exposed paddle should be connected
directly to the ground plane similar to that shown.
A sufficient number of via holes should be used to
connect the top and bottom ground planes. The eval-
uation circuit board shown is available from Hittite
upon request.
* R1 - R6 = 100 Ohm.
These resistors are optional
and may be used to enhance
decoupling of the RF path
from the control inputs.
