GaAs IC Control FET Series
DC–2.5 GHz
Features
s Low Cost SOT-23 Package
s Series or Shunt Configuration
s Low DC Current Drain
s Ideal Switch Building Blocks
s Pin Diode Replacements
s High Power Antenna Switches
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 device 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 applications as shown in the circuit examples on the
following pages.
