Description
The SKY13547-490LF is a single-pole, double-throw (SPDT) 75 Ωswitch. The high linearity and low
insertion loss of theSKY13547-490LF meet the most stringent requirements ofDOCSIS 3.1 applications.
The switch is a “reflective short” on the isolated port.
The SKY13547-490LF SP2T switch is provided in a
compact QuadFlat No-Lead (QFN) 2 x 2 mm package. A functional blockdiagram is shown in Figure 1.
Applications
Cable modem
Set-top box
Filter band switching
Relay replacement to switch between DOCSIS 3.0and DOCSIS 3.1 configurations
