RF1156

BROADBAND LOW POWER SP5T SWITCH

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.
