Single pole double throw switch

Single pole double throw switch：ATR5179

ATR5179 is a single pole double throw switch single-chip with a simple internal circuit structure. It is recommended to operate at a frequency of 20MHz-4GHz and is controlled by a single power supply. It has very low current consumption and insertion loss when the switch is turned on. The chip contains two control ports and three RF ports. The voltage of the two control ports V1 and V2 is in opposite phase, and different switching paths correspond to different states.

Application area ：Car positioning and navigation, active antenna, wearable devices, Internet of Things

Product Features：IP1dB=+ 30dBm@VC =3V ,IIP3=+ 43dBm@VC =3V, low insertion loss: 0.3dB@0.9GHz Ultra low DC power consumption, small packaging, low cost
