SKY13547-490LF

5 to 1800 MHz Ultra-High Linearity SPDT 75 Ω Switch

The SKY13547-490LF is a single-pole, double-throw (SPDT) 75 Ω switch. The high linearity and low insertion loss of the SKY13547-490LF meet the most stringent requirements of DOCSIS 3.1 applications.

The switch is a “reflective short” on the isolated port.

The SKY13547-490LF SP2T switch is provided in a compact Quad Flat No-Lead (QFN) 2 x 2 mm package.
