SW-439
GaAs High Isolation Switch
DC - 3.0 GHz
Features
• Low Power Consumption: < 15 µA @ +2.5V
• High Isolation: 50 dB Typical @ 2 GHz
• Low Insertion Loss: 0.7 dB @ 2 GHz
• Positive 2.5 to 5 V Control
• Low Cost Plastic MSOP-10 Package
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.
The SW-439 is fabricated as a monolithic GaAs
MMIC using a 0.5 micron pHEMT process. The
process features full passivation.
