Description

The SKY12208-478LF is a high power handling, Single-Pole,

Double-Throw (SPDT) silicon PIN diode switch. The device can

cover two frequency bands, 0.02 to 0.70 GHz or 0.05 to 2.7 GHz,

by changing the value of an RF choke in the SMT bias network.

The different Evaluation Board components for each band are

noted in Table 10.

The SKY12208-478LF features low insertion loss, excellent power

handling, and superb linearity with low DC power consumption.

The device is well-suited for use as a high power transmit/receive

switch in a variety of telecommunication systems.

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

Table 1.
