RFX333 Advanced Data Sheet 2.4GHZ CMOS SP3T ANTENNA SWITCH RF1 VC2 GND 12 11 10 DESCRIPTION VC1 1 9 GND ANT 2 8 RF2 VC3 3 7 GND 4 5 6 RF3 GND VDD RFX333 is a Single-Pole, Triple-Throw (SP3T) antenna switch developed in CMOS technology. The device is optimized for wireless applications requiring high linearity and low insertion loss, such as WLAN IEEE 802.11b/g/n and Bluetooth in the 2.4GHz frequency range. The RFX333 has simple and low-voltage CMOS control logic, and requires minimal external components. All DC-blocking capacitors are integrated on-chip to minimize PCB footprint. RFX333 is assembled in a small 1.6mmx1.6mmx0.45mm 12-Lead Quad Flat No-Lead (QFN) package. The ultra-compact size and low profile makes the RFX333 an ideal RF switch solution for Mobile Handset and Smartphone platforms.
