Description

The MASWSS0175 is a GaAs pHEMT MMIC DPDT

diversity switch in a lead-free 3 mm 12-lead PQFN

package. It is designed for low insertion loss and

allows for independent control and selection of each

switch path. It integrates blocking capacitors on all

RF ports and thus eliminates the need for additional

off-chip DC blocking capacitors.

The MASWSS0175 is ideally suited for applications

where very small size and low cost are required.

Typical applications are for WLAN IEEE 802.11a

systems that employ two antennas for transmit and

receive diversity.

This part can be used in all

systems operating between 4.5 GHz and 6.0 GHz

requiring moderate power and diversity switching.

The MASWSS0175 is fabricated using a 0.5 micron

gate length GaAs pHEMT process. The process

features full passivation for performance and

reliability.
