RF1604D is a single-pole four-throw (SP4T) switch designed for Receive Diversity switching applications. The RF1604D is ideally suited for battery operated applications requiring high performance switching with very low DC power consumption. The RF1604D features very low insertion loss with excellent linearity performance down to 1.3V control voltage. Additionally, RF1604D includes integrated decoding logic, allowing just two control lines needed for switch control. The RF1604D is packaged in a very compact 2.5mm x 2.5mm x 0.6mm, 12-pin, leadless QFN package. No DC-blocking capacitors are required on RF paths unless DC is applied externally to the device ports.
