Pin Out
Description
This group of GaAs control FETs can be used in both series and
shunt configurations. They incorporate on-chip circuitry that
eliminates the need for extra bias components and minimizes
power drain to typically 25 µW. These features make the devices
ideal replacements for PIN diodes, where low DC drain is critical.
Isolation performance degrades at higher frequencies due to
package parasitics. They can be tuned out in narrow band appli-
cations as shown in the circuit examples on the following pages.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
