Description:
M/A-COM’s MASW-007935 is a GaAs monolithic
switch in a low cost lead-free SOT-26 surface mount
plastic package. The MASW-007935 is ideally suited
for applications where very low power consumption,
low insertion loss and very small size are required.
Typical application is in dual band systems which
require switching between small signal components
such as filter banks, single band LNA's, converters
etc. The MASW-007935 can be used in applications
up to 0.25 Watts in systems such as CDMA, WCDMA,
PCS, DCS1800, GSM and other analog/
digital wireless communications systems.
The MASW-007935 is fabricated using a mature 0.5
micron GaAs PHEMT process. The process features
full passivation for increased performance and
reliability.
