Product Description
The RF1156 is a single-pole five-throw (SP5T) switch designed for general purpose
switching applications which require very low insertion loss and moderate power
handling capability.
The RF1156 is ideally suited for battery operated applications requiring high perfor-
mance switching with very low DC power consumption. The RF1156 features very
low insertion loss with excellent linearity performance down to 1.8V control voltage.
Additionally, RF1156 includes integrated decoding logic, allowing just three control
lines needed for switch control. The RF1156 is packaged in a very compact
3mmx3mmx0.85mm, 16-pin, leadless QFN package. No DC-blocking capacitors
are required on RF paths, unless DC is applied external to the device ports.
