Features
• Low Voltage Operation: 2.5V
• Low Insertion Loss: 0.3 dB at 1 GHz
• 2mm 8-Lead PQFN Package
• 0.5 micron GaAs PHEMT Process
Description
M/A-COM’s MASWSS0028 is a GaAs PHEMT
MMIC single pole three throw (SP3T) switch in a low
cost 2mm 8-Lead PQFN package. The
MASWSS0028 is ideally suited for applications
where low control voltage, low insertion loss, high
isolation, small size and low cost are required.
Typical applications are for filter and antenna
switching in handset systems that connect separate
receive functions to a common antenna, as well as
other related handset and general purpose
applications. This part can be used in all systems
operating up to 3 GHz requiring low control voltage.
The MASWSS0028 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.

5. External DC blocking capacitors are required on all RF ports.
6. Insertion loss can be optimized by varying the DC blocking capacitor value, e.g. 100 pF for 100 - 500 MHz, 39 pF for 0.5 - 3 GHz.
