Description
GND
GND
The M/A-COM SW-444 is a GaAs monolithic
switch in a low cost, FQFP-N, surface mount plastic
package. The SW-444 is ideally suited for
applications where very low power consumption,
high power handling, and low cost are required. The
SW-444 includes an integrated decoder. This switch
is designed for Transmit and Receive switching for
Triple-Band GSM/DCS/PCS Mobile Phones. The
switch offers GSM power handling as low as +2.0
V control voltage. The supply voltage VDD should
be connected to the highest available voltage and
may be unregulated.
VDD
The SW-444 is fabricated using a new 0.5-micron
gate length GaAs pHEMT process. The process
features full chip passivation for increased
performance and reliability.
