Description

M/A-COM’s MASWSS0202 is a broadband GaAs

PHEMT MMIC SPDT switch in a lead-free 3 mm

12-lead PQFN package.

The MASWSS0202 is

ideally suited for applications where very small size

and low cost are required.

Typical applications are for WLAN IEEE 802.11a

and 802.11b/g PC cards and access points. Other

applications include cordless phones and base

stations. Designed for high power, this SPDT switch

maintains high linearity up to 6.0 GHz.

The MASWSS0202 is fabricated using a 0.5 micron

gate length GaAs PHEMT process. The process

features full passivation for performance and

reliability.
