SKY13585-679LF

RF Switches Overview

The SKY13585-679LF is a single-pole double-throw (SPDT) radio frequency switch manufactured by Skyworks Solutions Inc. utilizing Silicon-On-Insulator (SOI) technology. It operates within a frequency range of 1 GHz to 6 GHz with a 50 Ohm impedance. Key electrical specifications include a typical insertion loss of 0.5 dB and a typical off-isolation of 38 dB at 2.5 GHz. The device supports a supply voltage of 1.8V to 3.3V and functions reliably between -40°C and +90°C. It is housed in a compact 6-MLPD (1x1) surface-mount package.
