Description
Switching is controlled by an integrated GPIO interface.
The SKY13412-487LF is a single pole, twelve throw (SP12T)
antenna switch with integrated GSM transmit harmonic filter. The
SKY13412-487LF maintains a high linearity, high isolation, and
low insertion loss performance, which makes it an ideal choice for
UMTS, CDMA2000, EDGE, GSM, and LTE applications.
Depending on the logic applied to the decoder, the antenna pin is
connected to one of 12 switched RF ports using a low insertion
loss path, while the paths between the antenna pin and the other
RF pins are in a high isolation state. No external DC blocking
capacitors are required on the RF paths.
The design features two dedicated GSM transmit ports. The
remaining ten ports are suitable for WCDMA transmit/receive and
GSM receive functions. Three transmit ports have been
specifically designed to provide optimal LTE Band 13
performance. The switch exhibits an excellent triple beat ratio and
2nd/3rd order modulation distortion performance.
The SKY13412-487LF is manufactured in a compact,
3.0 x 3.8 x 0.75 mm, 30-pin surface mount 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.
