Description
The SKY13581-676LF is a single-pole, double-throw (SPDT)
switch. No external DC blocking capacitors are required on the RF
paths as long as there is no DC voltage on the RF line. The switch
can operate over the temperature range of −40
C
to +85
C.
Switching is controlled by two CMOS/TTL compatible control
voltage inputs (VC1 and VC2). Depending on the logic voltage level
applied to the control pin, the RFC pin is connected to one of two
switched RF outputs (RF1 or RF2) by using a low insertion loss
path, while the path between the RFC pin and the other RF pin is
in isolation.
The SKY13581-676LF is provided in a small 9-pin,
1.1
1.1
0.5 mm QFN package.
A functional block diagram is shown in Figure 1.
