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,
W-CDMA, PCS, DCS1800, GSM and other analog/
digital wireless communications systems.

2. External DC blocking capacitors are required on all RF ports when using positive voltage control.
3. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 1000 pF for 100 MHz - 1 GHz, 39 pF for 0.5 GHz - 3 GHz.

6. External DC blocking capacitors are required on all RF ports
and GND. GND capacitors can be used with positive control
voltage to resonate lead inductance for improved isolation.
7. If negative control is used, DC blocking capacitors and GND
capacitors are not required.
Handling Procedures
Please observe the following precautions to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are sensitive
to electrostatic discharge (ESD) and can be
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
