GND
Package bottom must also be connected
to RF/DC ground.
RF1, RF2
These pins are DC coupled and matched to 50 Ohm.
Blocking capacitors are required if RF line is
not equal to 0V.

Vee
Supply Voltage -5V ±10%
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.
