Description

The MASW-010351 is an industry leading high

isolation single pole five throw (SP5T) switch. This

device design is optimized to take advantage of

separate GaAs pHEMT switch die and CMOS driver

die. The switch circuit design is symmetric and

combined with the separate CMOS decoder allows it

to maintain an excellent combination of insertion

loss and isolation for all states. This makes the

device ideal for band switching in multi-channel and

multi-mode base-station applications as well as

other applications where a compact, high isolation,

SP4T switch is required.

The MASW-010351 switch die is fabricated using a

mature 0.5 micron gate length GaAs pHEMT

process and features full passivation for enhanced

performance and reliability.

The MASW-010351 is offered in an industry

standard lead-free 4mm 24-Lead PQFN RoHS

compliant plastic package, which is ideal for high

volume surface mount reflow assembly.
