Description

The AS125-73 is a GaAs IC FET SPDT reflective switch in the SOT -6 plastic package for commercial applications. For positive operation it requires a fixed positive bias (V on the J1 line and DC blocks on all RF lines. This switch can also be operated with complementary negative voltage (no V S or blocking caps required).The AS125-73 provides a low cost solution for IF switching requirements in dual-band and dual mode subscribers.
