描述 Description

Please note: SKY12247-492LF is being discontinued and is not recommended for new designs. The suggested replacement is SKY12245-492LF The SKY12247-492LF is a compact, integrated high-powersingle-pole, double-throw (SPDT) switch with driver circuit forTD-LTE applications. The part operates with a single +5 V supplyand switches with a single control voltage (0 to 3 V).

This device features low TX and RX insertion loss, high isolationwith low DC power consumption and requires minimal externalcomponents, enabling a smaller PCB footprint.

The device is provided in a 5 x 5 mm, 20-pin Quad Flat No-Lead(QFN) package.
