Description
The SW-439 is a GaAs MMIC SPDT switch in a low
cost MSOP-10 surface mount plastic
package. This part is ideal for high isolation,
broadband switching requirements. Typical
applications include synthesizer switching, transmit/
receive switching, switch matrices and filter banks in
systems such as radio and cellular equipment, PCM,
GPS, and fiber optic modules.
Pin 1
C = 39 pF
The SW-439 is fabricated as a monolithic GaAs
MMIC using a 0.5 micron pHEMT process. The
process features full passivation.
4. For improved performance at frequencies below 500 MHz,
use larger value capacitors.
