Description

The SKY85614-11 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 SKY85614-11 operates at 5.0 V and draws 31 mA of 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.

A functional block diagram is shown in Figure 1.
