2V Dual-Mode WCDMA & Triple Band GSM/DCS/PCS Switch MASWSS0017
0.5 – 2.2 GHz
Features
• GSM Power handling with +2.0V Control
Voltage.
• Low Power consumption. Less than 1µA current
in Receive mode.
• Integrated Decoder.
• Leadless 4 x 4 mm FQFP -N, 20 Pin Package
• Low Insertion Loss of 0.3 dB in GSM Transmit
mode.
Description
The M/A-COM MASWSS0017 is a GaAs monolithic
switch in a low cost, FQFP -N, surface mount plastic
package. The MASWSS0017 is ideally suited for
applications where very low power consumption,
high power handling, and low cost are required. The
MASWSS0017 includes an integrated decoder. The
switch offers GSM power handling with below +2.5
V control voltage. The supply voltage VDD should
be connected to the highest available voltage.
The MASWSS0017 is fabricated using a new 0.5micron gate length GaAs pHEMT process. The
process features full chip passivation for increased
performance and reliability. This switch is designed
for Dual Mode WCDMA, Triple band
GSM/DCS/PCS handsets, where the phone needs to
be able to simultaneously receive a WCDMA and
GSM signal.
