2.4 to 2.5 GHz SPDT Switch with Low-Noise Amplifier

The SKY85201-11 is an integrated, single-pole double-throw (SPDT) switch with a low-noise amplifier (LNA) intended for wireless applications. The device has a low noise figure (NF) and offers the ability to add custom filtering between the switch and LNA blocks.

The SKY85201-11 operates at 3.3 V and draws low current. In the transmit mode, a shutdown function saves power when the device is inactive.

The FEM is manufactured in a compact, 2.3 x 2.3 mm, 16-pin Quad Flat No-Lead (QFN) package. The small footprint provides the industry’s smallest PCB area needed to implement an integrated broadband SPDT switch with LNA functionality.
