详细描述
The RF1147 is a single-pole four-throw (SP4T) switch designed for general purpose switching applications which require very low insertion loss and low power handling capability.
The RF1147 is ideally suited for battery operated applications requiring high performance switching with very low DC power consumption. The RF1147 features very low insertion loss with excellent linearity performance down to 1.8V control voltage. Additionally, RF1147 includes integrated decoding logic, allowing just two control lines needed for switch control. The RF1147 is packaged in a very compact 3mm x 3mm x 0.6mm, 16-pin, leadless QFN package. Unless external DC is presented to the device RF ports, no external DC blocking capacitors are needed.
