Description
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.
A functional block diagram is shown in Figure 1.
