Description
M/A-COM's MASWSS0033 is a GaAs PHEMT MMIC
SP3T high power switch in a low cost miniature FQFP
12-lead 3x3mm thin profile package. This package
represents a lower profile than standard FQFP style,
featuring a 0.8mm maximum thickness.

The MASWSS0033 is ideally suited for applications
where high power, low control voltage, low insertion
loss, high isolation, small size and low cost are re-
quired. Typical applications are for GSM and DCS
handset systems that connect separate transmit and
receive functions to a common antenna, as well othe
handset and related applications. This part can be
used in all systems operating up to 2.5 GHz requiring
high power at low control voltage.

The MASWSS0033 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process fea-
tures full passivation for performance and reliability.

Insertion Loss can be optimized by varying the DC Blocking Capacitor value, ie. 1000 pF for 100 MHz - 500 MHz, 100 pF for
0.5 GHz - 2.5 GHz.
