AS179-000 GaAs SPDT Switch 300 kHz–3 GHz Medium Power

The AS179-000 is a monolithic SPDT switch, fabricated using Skyworks proprietary GaAs PHEMTs as the switching elements. This wideband switch operates with RF signals from 300 kHz–3 GHz. The RF signal paths within the AS179-000 are bilateral. The J1 and J2 RF input/output terminals are reflective. Switching is controlled via a pair of high impedance control voltage inputs. Depending upon the logic voltage level applied to the control voltage pins, the common RF pin (J1) is connected to one of two switched RF pins (J2 or J3) via a low insertion loss path, while the path between the RF common and the other RF pin is in its high-isolation state. DC power consumption is very low, 100 μA nominal with control voltage of 3 V. The switch can operate over the temperature range of -40° C to +85° C.
