Description
The SKY12245-492LF is a compact, integrated high-power
single-pole, double-throw (SPDT) switch with driver circuit for
TD-LTE applications. The part operates with a single +5 V supply
and switches with a single control voltage (0 to 3 V). It can be
tuned to specific RF bands within the range of 0.3 to 3.8 GHz by
modifying select external SMT components.
This device features low TX and RX insertion loss, high isolation
with low DC power consumption and requires minimal external
components, enabling a smaller PCB footprint.
The device is provided in a 5
5 mm, 20-pin Quad Flat No-Lead
(QFN) package. A functional block diagram is shown in Figure 1.
