Description
M/A-COM’s MASWSS0069 is a GaAs PHEMT MMIC
single pole double throw (SPDT) switch in a low cost
miniature 4 mm FQFP-N 20 Lead package. The
MASWSS0069 is ideally suited for applications where
low control voltage, low insertion loss, high isolation,
small size and low cost are required. A typical application
is to replace mechanical relays in CATV systems. This
device has an additional state where both arms are off
and the device maintains a terminated and isolated state.
This state is achieved using a third control line. The
MASWSS0069 can be used in all 75 ohm systems oper-
ating up to 1 GHz.
The MASWSS0069 is fabricated using a 0.5 micron gate
length GaAs PHEMT process. The process features full
passivation for performance and reliability.
