详细描述
The RF1140 is a single-pole four-throw (SP4T) switch designed for general purpose switching applications which require very low insertion loss and high power handling capability. The RF1140 is ideally suited for battery operated applications requiring high performance switching with very low DC power consumption. The RF1140 features low insertion loss, low control voltage, high linearity, and very good harmonic characteristics. Additionally, RF1140 integrates decoding logic, which allows just two control lines needed for switch control. This part is based off RFMD’s GaAs pHEMT and is packaged in a very compact 3.0mm x 3.0mm x 0.55mm, 16-pin, leadless QFN package. No DC-blocking capacitors are required on RF paths, when no DC is applied external to the device ports.
