Description

The MASWSS0070 is a broadband GaAs pHEMT

MMIC SPDT switch available in a low cost 3 mm 12-

lead PQFN package. The MASWSS0070 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 MASWSS0070 is fabricated using a 0.5 micron

gate length GaAs pHEMT process.
