描述 Description

RFX333 is a Single-Pole, Triple-Throw (SP3T) antenna switchdeveloped in CMOS technology. The device is optimized forwireless applications requiring high linearity and low insertion loss,such as WLAN IEEE 802.11b/g/n and Bluetooth in the 2.4GHzfrequency range.
The RFX333 has simple and low-voltage CMOS control logic, andrequires minimal external components. All DC-blocking capacitorsare integrated on-chip to minimize PCB footprint. RFX333 isassembled in a small 1.6mmx1.6mmx0.45mm 12-Lead Quad FlatNo-Lead (QFN) package. The ultra-compact size and low profilemakes the RFX333 an ideal RF switch solution for Mobile Handsetand Smartphone platforms.
