Description
The SKY13445-368LF is a pHEMT GaAs switch. The device
includes a single-pole, triple-throw (SP3T) switch for 2 GHz WLAN
transmit, receive, and Bluetooth functions, and a single-pole,
double-throw (SP2T) switch for 5 GHz transmit and receive
functions.
Any of the RF ports can be used for any RF function regardless of
the port name. The SKY13445-368LF requires external DC
blocking capacitors on all RF ports.
Both the SP3T and SP2T switches are fabricated on the same
substrate. The active path is selected with five positive voltage
control lines (V1, V2, and V3 for low band switching, and V4 and
V5 for high band switching). In low band mode, the high band
paths are in isolation by applying a low voltage to the two control
lines, V4 and V5.
The switch is manufactured in a compact, 2 x 2 mm, 12-pin
exposed pad plastic Quad Flat No-Lead (QFN) 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.
