F2912 High-Reliability, High-Isolation SPDT RF Switch

Renesas’ F2912 is a high reliability, low insertion loss, 50 Ω, single-pole double-throw (SPDT) absorptive switch designed for a multitude of wireless and other applications. This device covers a broad frequency range from 0.009 MHz to 9000 MHz. In addition to providing low insertion loss, the F2912 also delivers excellent linearity and isolation performance while providing 50 Ω terminations to the unused input port.

The F2912 uses a single positive supply voltage of 3.3 V, supporting three states using either 3.3 V or 1.8 V user-selectable control voltage. An added feature includes a Mode CTL pin allowing the user to control the device with either 1-pin or 2-pin control.
