Description

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.

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.
