Description
M/A-COM’s MASW-007221 is a GaAs monolithic
switch in a lead-free SC-70 (SOT-363) surface
mount plastic package. The MASW-007221 is
ideally suited for applications where very low power
consumption, low insertion loss, very small size, and
low cost are required. Typical applications are in
dual band systems where switching between small
signal components is required, i.e. filter banks,
single-band LNA’s, converters, etc.

The MASW-007221 can be used in applications up
to 0.25 watts in systems such as cellular, PCS,
DCS1800, GSM, CDMA, W-CDMA and other
analog / digital wireless communication systems.
The MASW-007221 is fabricated using a mature 0.5
micron PHEMT process. The process features full
passivation for performance and reliability.

4. External DC blocking capacitors are required on all RF ports when using positive voltage control.
5. 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.
1000 pF capacitors used for positive control voltage. For
higher frequency operation, smaller value DC blocking capacitors can be substituted.
7. If negative control is used, DC blocking capacitors are not
required on RF ports.

†
Reference Application Note M538 for lead-free solder reflow
recommendations.
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.
