SKY85601-21中文资料SKY85601-21: 4.9 to 5.9 GHz SPDT Switch with Low-Noise Amplifier数据手册Skyworks规格书

描述 Description

The SKY85601-21 is an integrated, single-pole double-throw(SPDT) switch with a low-noise amplifier (LNA) intended forwireless applications. The device has a low noise figure (NF) withhigh linearity in the transmit mode.

The SKY85601-21 operates at 3.3 V and draws 15 mA of current.In the transmit mode, a shutdown function saves power when thedevice is inactive. The switch requires five external components.

The switch is manufactured in a compact, 2.5 x 2.5 mm, 16-pinQuad Flat No-Lead (QFN) package. The small footprint providesthe industry’s smallest PCB area needed to implement anintegrated broadband SPDT switch with LNA functionality.
