Description
The SKY13388-465LF is a symmetrical, single-pole, four-throw
(SP4T) switch. The device is designed for broadband, medium
power switching applications that demand high linearity and low
insertion loss. This is a general purpose switch optimized for
3GPP bands from 0.70 to 2.7 GHz.
Small, QFN (12-pin, 2 x 2 mm) package
(MSL1, 260 C per JEDEC J-STD-020)
The switch is manufactured with an industry-leading silicon-on-
insulator (SOI) process. The SKY13388-465LF features on-chip
energy management circuitry that uses only two control lines for
the switch operation. The low current consumption makes the
device suitable for battery-operated applications.
Skyworks Green™ products are compliant with
all applicable legislation and are halogen-free.

Definition of Green™, document number
SQ04-0074.
The SKY13388-465LF SP4T switch is provided in a compact Quad
Flat No-Lead (QFN) 2 x 2 mm package. A functional block
diagram is shown in Figure 1. The pin configuration and package
are shown in Figure 2. Signal pin assignments and functional pin
descriptions are provided in Table 1.
