RFX8051B数据手册RF/IF射频/中频RFID的射频前端（LNA+PA）规格书PDF

描述 Description

Please note: RFX8051B is being discontinued and is not recommended for new designs. The suggested replacement is SKY85712-11

RFX8051B is a highly integrated, single-chip, single-die RFeIC (RF Front-endIntegrated Circuit) which incorporates key RF functionality needed for IEEE802.11a/n/ac WLAN system operating in the 5.15-5.85GHz range. The RFX8051Barchitecture integrates a high-efficiency high-linearity power amplifier (PA), a lownoise amplifier (LNA) with bypass, the associated matching network, LO rejection,and harmonic filters all in a CMOS single-chip device.

RFX8051B has simple and low-voltage CMOS control logic, and requires minimalexternal components. A directional coupler based power detect circuit is alsointegrated for accurate monitoring of output power from the PA.

RFX8051B is assembled in an ultra-compact low-profile 3.0x3.0x0.55 mm 16-leadQFN package, and is the ideal RF front-end solution for implementing 5GHz WLANin smartphones and other platforms.
