SP4T High Isolation Terminated Switch

The MASW-010350 is an industry leading high isolation single pole four throw (SP4T) 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-010350 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-010350 is offered in an industry standard lead-free 4 mm 24-Lead PQFN RoHS compliant plastic package, which is ideal for high volume surface mount reflow assembly.
