Description

The SKY12211-478LF is a high power handling, Single-Pole,

Double-Throw (SPDT) silicon PIN diode switch with symmetrical

switching paths from a single common port. The device operates

over the 0.05 GHz to 2.70 GHz band. It features low insertion loss,

excellent power handling, and superb linearity with low DC power

consumption.

The SKY12211-478LF is well-suited for use as a high power

transmit/receive and RF path switch in a variety of

telecommunication systems such as WiMAX, TD-SCDMA, or LTE

base stations.

The device is provided in a 4 x 4 mm, 16-pin 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
