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.
Ordering Information 1
N/C
N/C
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.
