FM8544A - SP4T Switch

Download the FM8544A datasheet PDF. This datasheet also covers the FM8544A-ChipSourceTek variant, as both devices belong to the same sp4t switch family and are provided as variant models within a single manufacturer datasheet.

General Description

The FM8544A is a CMOS silicon-on-insulator (SOI),

single- pole, four-throw (SP4T) switch.

Off Ports, “Open Type” and ruggedness performance and extremely low Three pin GPIO control Interface for multi-on application insertion loss makes

Key Features

  • Broadband frequency range: 0.1 to 3.0GHz.
  • Low insertion loss: 0.70dB @2.7GHz.
